Is it possible to extend the cable for the TV? How to connect the antenna cable to each other. Connecting a TV cable with a plug

Correct connection - quality reception!

Due to incorrect connection of the antenna cable and plug, the quality of the signal deteriorates, or the TV completely stops receiving it.

In the video in simple language explains how to avoid similar mistakes, achieving stable reception and uninterrupted operation of the antenna. The author compares the two types of most common plugs, tells how to connect them to a cable so that the signal quality does not drop over time, and gives other valuable recommendations.

It clearly shows where the central core should be connected, and where the braid should be connected:

“There is a screw on the straight plug, under which some people simply clamp the core, and they squeeze the braid. It is not right. It is necessary to solder it to the outer part of the plug. Then you will have a good connection."

In addition to standard straight models, the video explains the features of working with angled antenna plugs. All elements are shown in close-up, as well as the junction of the braid and core with metal parts. Thanks to such a detailed examination, everyone will be able to understand the basic principles of connecting an antenna cable.

Television equipment cannot receive signals without an antenna connected to it. The connection is made through a special wire, which can wear out over time. If its life has come to an end, you will need to reconnect the television cable to the outlet.

Antenna wire device

The antenna wire that needs to be connected to the TV socket differs from other types of cable products in design:

The main component is the conductor. It is made in the form of a conductive wire made of copper. It is located inside the device and is used to transmit impulses.
Insulating layer. It consists of a dielectric material designed to separate conductive elements. The insulating layer is used as a frame, securing the location of the conductive components relative to each other.
Shielded layer. Usually made from several materials at the same time. This can be foil, aluminum and copper.
Shell. Another insulating layer designed to protect the conductor from various external influences.

Coaxial conductor device

The coaxial type of conductors is divided according to characteristics:

outer diameter of the product (to connect to the antenna, you must use a 6-8 mm cable);
wave resistance value;
product shielding parameter;
flexibility.

To connect to the antenna and connect the television cable to the outlet, you should not use a conductor of the RK-75 type. Such products are characterized by increased pulse attenuation. The wire purchased is less flexible, and its braiding should be as dense as possible, otherwise it will allow interference to pass through.

How to prepare a television cable for connection to an outlet?

Before connecting or extending coaxial wire to the adapter, it must be prepared. To do this, the outer shell of the product is removed, after which the screen itself is carefully assembled and twisted. To prepare the screen, the braided layer and foil must be removed, leaving only part of the inner insulating layer. All layers are removed from the screen down to the conductor core, the length of the remainder for connection is selected by the user.

Self-connection diagrams for television cable

There are two ways to perform connection operations to satellite sockets:

loop method;
by using a star circuit, but to implement it you need to additionally install a splitter.

Train

The daisy-chain connection scheme allows you to combine several TVs to connect to one antenna. This requires multiple feedthroughs and one end outlet. From the diagram you can determine its main drawback. If the contact breaks at one of the points, then the signal will not flow further along the circuit. In addition, the incoming pulse will be more powerful and stable only on the first few sockets, then it will gradually fade away.

But this drawback can be removed. You can increase the quality of the image displayed on the screen by using a more powerful, increased input pulse. The main advantage of this scheme is savings Money during its implementation. Also, the user will need less time to lay the wire from the antenna to the TV itself.

Loop connection diagram

Star scheme

To implement this scheme, you will need a splitter or divider. Its installation gives the consumer the opportunity to divide and increase the power of the input pulse into several signals that are equivalent to each other. From the divider, further according to the diagram, an antenna socket is installed for each TV located in the room. The main advantage is that the price of single splitters is usually lower than end and pass-through devices.

If the signal is disrupted for some reason, this will not affect the operation of other television equipment. This circuit can be called more reliable compared to the loop circuit. Despite the fact that more wires will be needed, this circuit has more advantages.

Installation instructions

Laying coaxial wire can be done in several ways:

Hidden installation. To do this, the cable will be hidden in the wall, and the internal type socket will be mounted in the socket box.
In an open way. A plastic or metal box will be used to lay the wire; the first option is more preferable for residential premises. The connectors are connected to the overhead socket.

The antenna wire is laid at a minimum distance to the television equipment and away from power lines.

To perform installation work you will need the following tools:

Side cutters or stationery knife. Used to remove the insulating layer.
Phillips head screwdriver.
Drill with a set of drills. You will also need a special nozzle, which will be used to make holes for installing the mounting box if a hidden installation method is used.
Fastenings. The type of fasteners is selected by the consumer taking into account the material from which the walls are made. For concrete and brick surfaces, dowels will be required. If the walls are made of wood, then you will need self-tapping screws.

The installation procedure is as follows:

The socket box is installed. It is necessary to calculate the location of the outlet; markings are made using a pencil.
The attachment is installed on the drill, and holes are drilled using the tool. The depth is selected taking into account the height of the socket box.
The recess made must be thoroughly cleaned of dust residues, and the box is installed.
The socket box is fixed; for this, the dowel is installed in the drilled hole.
Then you need to insert a wire approximately 10 cm long into the box.
The cracks around the box must be sealed with a putty solution.
After installing the socket box, the wire is cut. At a distance of 3 cm from the end of the cable, an incision is made into the sheath with a utility knife. The plastic braid is dismantled, it can be removed by hand, then it is separated.
Then, approximately 1 cm from the edge of the cable, it is necessary to remove the layer of braiding and insulation of the conductor. The procedure for cutting the sheaths must be performed carefully and carefully, since if cuts remain on the core, this will lead to a decrease in the quality of contact. Subsequently, the conductor may be broken. When performing the task, make sure that the cores and the foil layer do not short-circuit.
The front panel is removed from the socket. The main conductor must be connected to the connector, which is located in the middle of the back of the device. The core is fixed using a bolt. The braid itself is secured using a special clamp.
The device body is installed in the box, then the spacer bolts are tightened. When installing, please note that the main surface of the outlet must be mounted flush with the plane of the wall. The outer frame is fixed, then the performed actions are diagnosed.
If a surface-mounted socket is used, the installation procedure is carried out similarly, and the whole process will be simpler.

Sergey Efimov spoke in detail about connecting a television outlet and its installation.

Will the signal deteriorate when extending the cable?

If an extension cord was used, the quality of the transmitted signals is lost. To ensure data transfer without loss, experts advise making no more than two connections. But ideally it is better to use a solid wire.

How to extend a television cable yourself?

If necessary, several pieces of coaxial wire can be spliced together. There are several methods available to accomplish this task.

Connection via adapter

We correctly connect several parts of the conductor for extension through an adapter connector:

The insulating layer is removed from both ends of the cable. Then the foil component, as well as the braid, are wrapped in reverse side. The inside of the aluminum foil is covered with a thin layer of polyethylene or lavsan. Half of the foil layer should be wrapped back to ensure quality contact. This is done so that the side that conducts current is on the outside.
The internal insulating layer is removed up to the signal cable; the length should be 10 mm. It is necessary to exclude the possibility of undercutting of the copper component, since this will lead to a decrease in strength.
When the ends on the wire are prepared, special F-connectors are installed through the foil layer. The main core of the conductor will protrude 0.5 cm from the plug. If it is larger, it must be cut off.
The final step will be screwing the ends from the F-connectors to the adapter device.

Extension via plug-to-socket connection

You can extend the conductor after connecting the television cable to the outlet without a soldering iron, using the extension method through connecting the socket to the connector. To complete the task you will need the nuts that were used in the previous method.

How to connect the cable to the plug?

Nuts are screwed onto the ends of the conductor, the television connector is fixed to one of them, and the socket to the other. The next step will be to connect them. To ensure high-quality contact, the connection point must be wrapped with insulating tape. This extension option is unaesthetic, but is characterized by high reliability. It is better to hide such connections in cable ducts so as not to disturb the interior design.

The connectors are used angled or straight, the method of installation on the conductor is identical. Angled options are used for more convenient connection when a straight connector is inconvenient to install. These plugs can be used to provide convenience when making sharp turns.

Alexander Viktorovich AV showed the procedure for connecting the antenna cable to the plug.

Extension using a splitter

To make connections to a splitter without soldering, you can use a divider. A divider or splitter is a device made in the form of a metal box. The device is equipped with one In connector, as well as two Out sockets; their number can be more than two. If you have a certain number of TVs, you should not buy a divider with additional Out connectors in reserve, as this will lead to a deterioration in the pulse.

An external conductor is connected to the In contact; it will be solid without extensions. The divider is fixed to the surface of the wall or floor, this will prevent the possibility of damage to the wiring. The separating device is equipped with butt nuts that are installed on the ends of the conductor; they must be prepared in advance. After winding, the ends of the cable are connected to the connectors. The final connection of the input to the external conductor is made, and the outputs to the TVs.

If there are more than two TV devices in the room, then it is necessary to use an active splitter device.

Such devices are equipped with special amplifiers that increase the quality of transmitted signals. The splitter is mounted closer to the television equipment and connected to the household network. Regardless of the method of connecting conductors, the consumer must ensure fast access to the device if repairs are necessary.

Twist

You can connect the old conductor to the new one by twisting, but this option is less reliable. Its implementation will not provide effective protection of the electrical circuit from external interference. For better quality, you need to solder the junction with tin and rosin and install it away from the electrical circuit. After soldering, the twisted area is wrapped with electrical tape.

The twisting method is best used for one TV. If you are wiring to several TV devices, then the connection point must be installed in the distribution panel. All electrical circuits must be insulated to prevent contact between them.

User san4ezize talked about twisting a television conductor to connect to an antenna.

How to connect a TV cable to an amplifier

The procedure for connecting a conductor to an amplifier device is as follows:

The coaxial wire is cut. The insulating layer is removed from the ends of the cable with a utility knife. The braiding of the conductor located under the insulation layer must not be damaged.
A section of the cut outer insulator is removed, everything except the core is removed back.
5 mm is marked from the shifted end of the braid, the inner insulating layer is removed.
The end of the conductor is installed under the clamp of the amplifier device connector; in the example, we use a power supply from a PC. The steps are carried out carefully; when performing the task, the installation of the main core in the mount must not be allowed. The aluminum braid must not come into contact with the area from which the insulation has been removed.
The bolts are clamped, the conductor contacts are attached to the amplifier.

Wire laying rules

When performing a task, the following rules are taken into account:

The cable is laid away from household wiring. Laying electrical circuits near powerful electrical equipment is not allowed.
When connecting and laying, the cable length is thought out in advance. The number of connections on the line is minimal.
For installation, exclusively factory connecting plugs and splitters are used.
The intersection of cables with power circuits is allowed only at an angle of 90 degrees.
Do not roll the conductor into turns or bend the cable.
In the junction box, the connection procedure is performed exclusively by soldering. The conductor should not be exposed too much.

The TV itself cannot receive signals. To do this, an antenna is installed in front of it, which is connected via a cable. Its service life under normal operating conditions is about 10 years. When it is outdoors and exposed to the elements, replacement will be required much sooner. The cable fails especially quickly when suspended.

The photo below shows a modern television cable.

Installation of a modern television cable

It is prohibited to use a suspended cable without a support cable.

Used for difficult climatic conditions special cable, which should be indicated in the characteristics.

Cable device

In the center of the core there is a central copper conductor with a diameter of 0.3 to 1.1 mm (signal wire). It is not recommended to take a smaller size, since it is designed for the frequency of the meter range. Through a thin cable, the TV will show only the main channels. It is better for the user to choose a thicker cable that has less signal loss.

On top there is a shielding layer of aluminum foil and a braid of thin copper wire, which protects against external interference in the form of electromagnetic waves. Between the central wire and the screen there is a layer of polyurethane insulation. Outside there is another insulation made of polyvinyl chloride or polyethylene to protect the cable from mechanical stress and ultraviolet radiation.

The cable must have foil and braid as a screen. Old-style products with a single braid are not suitable for modern video signal transmission standards.

The centers of the wire and the screen coincide in the radial direction. Due to this, losses of the transmitted signal are reduced.

Coaxial cables differ in the following parameters:

outer diameter (best sizes - 6-8 mm);
wave resistance;
degree of shielding;
flexibility.

The markings of common television cables are as follows:

imported – RG-6, RG-59;
domestic - RK-75 (75 Ohm - wave impedance value).

It is not recommended to purchase the RK-75 cable, as it has a high signal attenuation rate. In city conditions, this may not be noticed due to the close location of transmitting stations, but in rural areas Signal loss becomes noticeable.

When laying a television cable near electrical wiring, its diameter must be at least 10 mm and have increased protection against interference.

When choosing a cable, you should pay attention that it is not too flexible. The braid should be chosen more densely. Too rare - it easily misses interference. The foil should not be very thin.

The insulation of the central core should be hard, not soft like foam rubber.

When studying the passport data, attention should be paid to the frequency and amount of attenuation TV signal at a certain length. The lower they are, the higher the quality of the cable.

How to extend a TV cable

When lengthening the cable, you must remember that this leads to a decrease in quality transmitted signal. It is recommended to create no more than 1-2 connections. The photo shows different types devices for connecting and branching cables.

TV cable connectors and splitters

The insulation layer is removed from both ends and the copper braid and aluminum foil of the screen are wrapped in the opposite direction. The inner side of the foil is covered with a thin layer of polyethylene or lavsan. To ensure reliable electrical contact, half of the foil should be folded back so that the conductive side is on the outside for better contact.
The internal insulation is peeled off down to the signal wire in a section 1 cm long. In this case, it is necessary to prevent the formation of undercuts in the copper conductor, which reduces its strength.
After preparing the ends, F-plugs are screwed onto the cable through foil (Fig. a). The central core should protrude 5 mm from the plug. If it turns out to be longer, it should be trimmed.
Screwing the ends with F-plugs onto the F-socket adapter (Fig. c).

Splicing a television cable: a – F-plug; b – F-socket adapter; c – detachable connection

Connection of plug and socket

The same nuts are screwed onto the ends of the cables as in previous method, but a TV plug is screwed onto one of them, and a TV socket is screwed onto the other. Then they are connected. To make it reliable, it should be wrapped with electrical tape. The photo shows connections wrapped with electrical tape. They don't look very attractive, but they are reliable. Usually they are hidden in cable ducts.

Wrapping cable connections with electrical tape

Plugs are available in straight and angled versions. They are mounted on the cable in the same way. Angled - used for ease of connection, where a straight plug is not always convenient to use, as well as when creating complex turns.

Angled plug is used where using a straight plug is difficult

Twist

This method is the worst because the connection is not protected from electrical interference. It is better to solder it with tin and place it away from the electrical wiring. If wiring to several TVs is done in this way, the connections are made in the junction box. In this case, the screen and central wires are carefully insulated from each other.

Wiring via splitter

A splitter is a metal box with one “IN” input and two or more “OUT” outputs.

An external cable is suitable for the input, which should not have any splices. The splitter is attached to the wall or floor so that there is no danger of tearing out the cabling. The connector comes with butt nuts. They should be screwed onto the pre-prepared ends of the cables and then connected to the plugs. Next, the input is finally connected to an external cable, and the outputs are connected to television receivers.

TV cable splitter

If the number of TVs in the house exceeds two, instead of the usual one, install an active splitter containing a video signal amplifier. It is placed as close to the receiver as possible. This splitter is connected to the mains power supply.

With any method of connecting cables, easy access must be provided in case of repair.

Cable laying rules

Away from electrical wiring and powerful electrical appliances.
Minimum number of connections.
Use only factory splitters and connectors.
Intersection with power contours is allowed only at right angles.
It is not allowed to twist the cable into turns or bend it at an acute angle.
In the panel box, the connection is created only by soldering and with minimal exposure of the cable.

Cable preparation. Video

How to prepare antenna cable TV or satellite for use, the video below will tell you.

You can extend and branch a television cable with your own hands if you follow the rules described in the article.

Do you still watch TV? Despite the increasing popularity and accessibility of the Internet, the share of television viewers in Russia is not decreasing. The expansion of thematic channels has led to the individualization of preferences - everyone can now find a program to suit their taste. But what to do if the antenna cable was chewed by a dog or you bought another TV to install in the next room?

The reason for the need to connect the antenna cable may also be redevelopment in the room, when you need to add the missing length. There are several ways to accomplish this: using F-connectors or a splitter, soldering or twisting contacts. I will tell you each of the sounded methods with the nuances of their application. Don't switch!

Radio mechanics identify the following options for connecting and extending the antenna cable:

F-connectors are a special metal structure that allows you to reliably connect two pieces of cable without the use of a soldering iron or additional insulation. The method is often used when, when moving the TV to the other end of the room, the available supply of cable is not enough or the damaged section needs to be replaced. This is the simplest and most economical method, as opposed to laying a new cable directly from the antenna.
Splitter - used to evenly divide the signal coming from the antenna into two TVs. Connection to the device is made using F-plugs.
Soldering is a cheap but at the same time reliable connection method. To implement it, you do not need to look for adapters and other components; usually everything you need is already available at home. It is possible to connect any shielded cables: with a different number of central cores, diameter, type of screen (for example, copper braid and aluminum foil).
Twisting is the least preferable method of all presented, since it leads to a strong loss of signal quality. Due to its unreliability, it can only be considered as a temporary solution, in the absence of F-connectors or soldering tools.

With the transition of analogue broadcasting to digital form, the requirement of televisions for the broadcast signal has increased. Residents of suburbs and villages now use TV tuners with amplifiers. Therefore, the quality of the connection of television wires came to the fore.

Extension of TV cable using F-connectors

This option for connecting the wire involves visiting a store where you need to purchase two F-plugs (for each of the 2 ends of the cable) and one adapter - F-socket. It is recommended to take a piece of TV cable with you, since components are sold for different diameters. The tools you will need are a regular or construction (segment) knife and wire cutters.

Building up an antenna cable begins with preparing its sections:

Make a careful cut into the outer shell. For ease of operation, the length of the cut should be greater than the length of the F-plug body. In the future, it can be adjusted by removing the excess part of the central core.
Fold the casing in the opposite direction and remove it completely.
Turn the copper shield and the foil underneath towards the remaining outer shell. To perform the procedure, they can be slightly incised. At this stage, pay attention to possible availability coatings made of a thin layer of polyethylene or lavsan on the inside of the foil. These materials greatly impair the transfer of contact to the F-plug housing. To solve the problem, screw back half of the wrapped foil. This way the side with poor current transmission will be on the inside.
Using a sharp knife, cut the insulation of the central core. Try not to leave notches on it, as they reduce strength and can lead to breakage.
Take the F-plug and screw it onto the cable. It must fit snugly, since the fixation is achieved only by clamping force.
Trim off any excess center core. Its edge should protrude 3-5 mm beyond the F-plug body.

If the diameter of the cable is smaller than the internal diameter of the F-plug, then before turning off the screen with foil, wrap electrical tape around the outer sheath.

This completes the preparation of the two ends of the cable. Now take the F-socket and connect the first and second plug to it. Fixation is ensured by screwing the movable head of the F-connector onto the thread of the adapter. The result will be a neat and reliable connection. In its place, you can also install a splitter, which will be discussed later.

Extending the cable using a splitter

This device is designed to distribute the input signal evenly. Accordingly, it has one incoming connector (labeled with the word “IN”) and several output connectors (labeled with “OUT”). Using a splitter, you can not only extend the cable, but also route it to two or three TVs at once.

The inlet hole on the splitter itself is similar in principle to the F-socket. Fixation occurs due to a threaded connection. The process of extending the cable is similar to that described for F-connectors, so there is no point in dwelling on it separately.

Connecting TV wires by soldering

For this method you will need a soldering iron, solder and rosin (an alternative is soldering acid). You should also have basic soldering skills.

The method allows you to connect different cable variations. Let's consider step by step the process of soldering two cables with a single core and a double screen (copper braid + aluminum foil):

On each cable, make a cut along the outer sheath 5-6 cm long.
Unscrew the shell and the screens underneath it - copper mesh and foil.
Cut the central core along with the insulation to a length of 2 cm.
Cut off part of the insulation from the central core - the result will be some kind of step. When folding two parts of the cable, this design should ensure complete closure of the contact, with virtually no gaps.
Bend the central core away from the insulation by 45 degrees. Tin it and solder it to the second part of the wire. In the absence of an assistant, before soldering, the cores can be tied with thin wire taken from a copper screen.
Inspect the soldering results. If the cured solder has sharp edges or beads, remove them using fine-grit sandpaper or a file.
Close the two steps cut from the insulation together, removing excess if necessary. Secure the resulting structure with insulating tape - 2-3 turns.
Put the foil back on the two parts of the cable. On the inside it is covered with a non-conducting layer, so you need to properly wrap this part of the screen, ensuring contact between the conductive sides.
Return the copper mesh - first one, then the other. To improve contact, wrap the area with several pieces of tinned wire of the same diameter. Then solder these parts.
Unscrew the outer shell one by one. As a result, one should envelop the other. Secure the connection with insulating tape.

At the output, you will get a durable and sealed junction, which has virtually no effect on the quality of signal transmission.

Expert opinion

Egor Razumny

I know how to assemble and disassemble computers, laptops, tablets, phones. Sometimes successfully. I have mastered the skills of diagnosing breakdowns with using Google and Yandex.

Of course, soldering is stupid. There are no problems with the central copper core, but the braid is usually made of aluminum alloy, which is almost impossible to solder. But if you really need it, the recipe is this: wind several turns of tinned wire onto pre-twisted braided pieces. Tin this area and, after cooling, flatten it with a hammer. I recommend using the SAT-703 cable from the Italian company “CAVEL” with a linear attenuation of 16.5 dB/100 m. The central core is copper. Braid - tinned copper. In this case, both conductors are soldered with ordinary rosin.

Twisting method

Use this option only as a last resort, when you need to immediately provide a signal to the TV, and you don’t have F-connectors or a soldering iron with solder at hand. Twisting in any case will lead to a significant loss of signal quality, and during the connection of the central core it often breaks.

In general terms, the twisting technique is similar to soldering. You will need to prepare the two ends of the cable in a similar way, then fold them parallel to each other. First, twist the copper mesh and insulate the area with PVC tape. Then the central cores are connected. Considering the temporary nature of the work and the good insulation of the copper screen, the cores can be left as is - bending them to the outer braid is fraught with a break.

These are all methods that can be used to extend the antenna cable. The most simple option is the use of F-connectors - they are not expensive, and do not require special tools for installation. I recommend soldering when connecting two wires with different characteristics. To split the signal to several TVs, use a splitter. Twisting is a temporary method that should be replaced with a more reliable one in the future.

In order for the TV to show, you need to connect an antenna to it. For this purpose, the TV has a connector for connection, the so-called antenna socket. The other part of the connection, the plug, is mounted on the antenna cable, which actually connects either to the antenna, even a satellite one, or to the distribution box of the cable television network, if the owner is connected to it.

In contact with

TV plug

Previously, in order to connect a plug to a cable, it had to be soldered. Then they began to use antenna connectors, which are mounted by soldering bases. In the first models of this part, the central antenna wire core screwed to the contact with a screw. And finally, they now use international standard type F plugs. Strictly speaking, this connector is simply a bushing that consists of two parts and is screwed onto the antenna wire.

In order for the TV to have a high-quality picture and the signal not to be lost, it is necessary to ensure that there is good contact at the connection point. If this seemingly simple task is not solved correctly, the TV will operate with noise in both image and sound.

To properly connect the antenna wire to the TV, it is not at all necessary to call a specialist. All manipulations It is possible to make it yourself using simple tools that everyone has.

To solve this problem you will need:

antenna cable (otherwise known as coaxial cable).
F type plug.
knife or stationery cutter.

What is a cable?

The antenna cable is a multilayer wire that, due to its shielding properties, can transmit a stable signal. Consists of a central core, copper wire, dense plastic insulation, aluminum foil (the second conductive element), shielding braiding, which dampens interference and final external insulation, and protects from weather and mechanical influences.

The market now offers a wide variety of these products, both domestically produced and imported.

How to prepare the cable

Having everything you need, you can start connecting the antenna to the TV. Connect the plug to antenna cable satellite or other antenna, possibly in two ways: by wrapping the shielding braid and without wrapping it. It would be better and more reliable for contact to wrap the shielding braid, but if this fails, you can not wrap it.

In order to cut the cable, take a knife or cutter and, stepping back 1–1.5 centimeters from the end of the cable, carefully cut the outer insulation in a circle.

The main thing is not to damage the braid and aluminum foil. Remove the cut insulation. Now the exposed part of the braid and foil must be wrapped back onto the wire itself. There is one nuance here. To make the foil stronger, it is covered with polyethylene on the inside. It is impossible to clean the plastic layer without damaging the foil. If you simply push the plug onto the unscrewed part of the foil, the contact will be unimportant or, in general, bad.

In order to avoid this, you need to bend half of the foil back and the conductive part will be on top. Then we remove the central core from the insulation, retreating 0.5–1 centimeter, again trying not to damage the wire itself. Now we wrap the first half of the plug onto the foil. We make sure that the central wire gets into the core of the plug. After, “bites off” with pliers part of the central core, so that it protrudes from the union nut by 4–6 millimeters. Finally, screw the second part of the plug until it stops. And our antenna plug is ready for use. Can also be used for satellite dishes, and for analog TV.

If the foil is not wrapped, then the top insulation is simply cut off, the braiding is removed and the plug is screwed onto the open section of the cable.

If you happen to have a plug of a previous modification in your hands, which also did not require soldering. It must be connected to the TV cable as follows. Disassemble the plug by disconnecting the plastic half. Place this plastic part on the wire first.

How to connect a TV to an antenna cable

To connect the TV to cable television, cable required. At its end you need to install an F plug, specially designed for a television antenna. If the user not very good at understanding In this matter, it is better to seek help from specialists. Because if you do this job incorrectly, then both analog and digital signals will not work correctly, causing the image quality on the TV to be lost.

The choice of cable is of great importance. Even a TV of the latest brand and correctly placed F plugs on the ends of the cable cannot give an excellent picture if a low-quality cable is used. And what kind best cable, and how can you recognize it among the many offered on the market?

To do this you need to have an idea of how high frequency TV signal current flows through the cable. And the higher this current indicator, the closer it goes to the surface conductor. Due to the low height of the television signal in the antenna cable and its high frequency, it is impossible to determine without special instruments. You can determine whether there is a signal or not by connecting the antenna to the TV.

The most purchased and widely known on the market are cables with a characteristic impedance of 75 Ohms, which are excellently used for receiving and transmitting television signals. Marking is done depending on increasing quality. It is usually applied to the top layer of the antenna cable along its entire length, every linear meter next to the digital meter mark.

If the consumer has the skills to work with wires and certain knowledge, then he can easily connect the TV to the antenna on his own. The main thing is to follow the instructions and not deviate from the rules.

It is important to remember that the voltage of the television signal in the antenna wire is millionths of a volt. Therefore, such a cable does not pose a danger to human life.

It happens that after the antenna plug is inserted into the TV socket, it becomes impossible to move it closer to the wall, because the cable is in the way. In order to get rid of this problem, you should use a special F-socket, that is, a plug of an angular design.

These two plugs are essentially the same thing, and they are installed in the same way. The only difference between them is in form.

But before their appearance, other plugs were used, the connection technology of which was completely different.

Is it possible to do without a plug?

There are times when you urgently need to connect a cable to your TV, but you don’t have a soldering iron. It turns out that you can do without his help. This will require just remove the top layer shell and remove the braid. Then remove the insulating layer from the central wire of the cable. The wire itself must be folded into a loop, the width of which is slightly larger than the hole in the TV connector socket.

Which antenna plug is preferable?

Definitely the best plug for a television cable is the F plug. His the advantages are implementation of excellent quality television signal, as well as ease of installation. Which is undoubtedly more popular among home craftsmen.
