Examples of making a television splitter with your own hands. Antenna splitter Antenna splitter buy

You will need

• - antenna splitter;
• - television cable;
• - plugs;
• - knife.

Instructions

Select the location where you plan to install the antenna splitter. Mark the future locations of the splitter and your television receivers.

Take a tape measure and measure the distance to each of the TVs that you will connect. Write down the result. Add up the measurement results. You have the total cable length. Add a couple of meters to this number for insurance.

Buy the required amount of cable, as well as everything you need: a splitter, plugs (according to the number of TVs), mounting brackets (if you are going to attach the cable to the wall). When purchasing, check whether the inner diameter of the splitter nuts matches the outer diameter of the cable.

Cut the cable into pieces to suit your size. Using a sharp knife, remove the outer sheath from the end of the cable. Separate the foil screen and braid from the center and bend it onto the uncleaned part of the cable. Be careful not to accidentally cut them. Also remove the insulation from the central part of the cable.

Place the splitter nut on the end of the cable. Bend back the screen and braid. Insert the center core of the cable into the splitter socket and tighten the nut. Repeat these steps with the remaining sections of cable. Secure the splitter in the chosen location.

Connect each piece of cable to the TV for which it is intended. If necessary, secure it using purchased staples or place it in the cable channel of the baseboard.

Install the plug on the free end of the cable. To do this, prepare the cable as described above. Replace the plug cap. Bend back the screen and braid. Insert the central wire into the hole in the plug and secure with a screw. Crimp the braid around the cable sheath with a bandage. Screw the cap onto the body. Insert the plug into the antenna socket of the TV.

Turn on all television receivers to evaluate the reception quality. If it does not meet your requirements, you need to install an antenna amplifier.

Antenna splitter - purpose and main differences

The general concept of antenna splitter (crab) means three types of devices:

• splitters (dividers);
• diplexers (adders);
• couplers (tap).

Each of them serves to solve specific problems.

Purpose and main differences

Splitters allow you to evenly divide a television signal between several outputs. For example, if the input signal level was 12 dB, then at the outputs of a double divider it will be 6 dB, a triple divider - 4 dB, and a quad divider - 3 dB.

Double splitter

The figure shows a schematic representation of a double splitter, where:

A – signal input;

B and C are the exit.

Antenna splitters of this type are used in cases where it is necessary to send a signal to 2 or 3 TVs, or more if the device has an amplifier (active splitter). An example is the model of the Polish manufacturer ARA-01A.

Diplexers allow you to combine two signals into one. Most adder models are universal; they can work in two directions, that is, act as an adder or a divider.

Dual diplexer

The figure shows a schematic representation of a double diplexer, where:

A and B – input signals;

C – output signal.

A diplexer is used in cases where it is necessary to run a signal from a satellite and a conventional antenna over one cable or combine signals from different ranges. The figure shows an example of using an adder and a divider together, where:

• A – television antenna;
• B – satellite dish;
• C – adder;
• D – socket with a built-in divider for connecting two television cables.

Scheme of joint use of an adder and a divider

Tappers are used to organize a backbone television network, for example, to divert a signal to apartments in a multi-storey building.

Highway organization diagram

The figure shows an example of organizing a highway using several taps, where:

• A – incoming signal;
• B, C, D, E, F, G, H, I, J – signal output (tap), for example, to each floor of a nine-story building.

As can be seen from the connection diagram, such devices have one pass-through output, from which the signal is supplied to the input connector of the next coupler.

Antenna splitters can also include a range blocker (stub), which is widely used by cable television operators to separate social and paid connection packages.

In everyday life, splitters are most often used; they are used to connect several televisions to the antenna cable entering the apartment; the quality of the television signal directly depends on these devices.

How to choose

First of all, it should be taken into account that the operating frequency of antenna splitters for digital television and satellite dishes is different. For the former it is limited to 1 GHz, for the latter it is 2.5 GHz. In addition, the satellite splitter may have a “Powerpass” function (allows you to supply power to the satellite dish head).

Note that a satellite splitter can also be used to split a digital or analog signal.

The second parameter that you should pay attention to is signal attenuation; as a rule, its value is indicated on the device body; the lower it is, the lower the losses.

It is also important who the manufacturer of the device is. Products from such well-known manufacturers as: Lans, Rexant, Premier, TAH, Luxmann, Alda, Hama, Sat, etc. will give an output signal an order of magnitude better than Chinese or homemade splitters.

How to connect

The instructions for connecting the splitter are quite simple:

• select a location and attach the divider to it;
• Next, you need to remove the plug from the antenna splitter (do this operation for each connector);
• use a coaxial cable (adapter) to connect the input to the TV and the jack;
• connect the television cable entering the apartment.

Do it yourself

It’s not difficult to make a splitter for analog television with your own hands; here are some simple diagrams of such a device.

Passive splitter with resistors.

Separator circuit for two and three devices

The figure shows two diagrams:

• a – for connecting two TVs (R1, R2, R3 = 25 Ohm);
• b – for connecting three TVs (R1, R2, R3, R4 = 36 Ohm).

Below is an example of a printed circuit board layout for circuit “b”.

Splitter board for three devices

The assembled device must be placed in a special case (any metal box will do for this), which should preferably be grounded. If the grounding is incorrect, interference in the form of snow may occur. Actually, it is better not to ground at all than to do it incorrectly.

If the image on the TV screen is double, you should put a ferrite ring on the coaxial cable between the splitter and the TV.

Active splitter circuit.

In cases where you have a low level of the incoming television signal, you can correct the situation using a divider that has a broadband frequency amplifier. The diagram of such a device is shown in the figure below.

Divider circuit with antenna amplifier

Parameters of the elements indicated in the diagram:

• R1-10 Ohm;
• R2, R4, R5 – 430 Ohm;
• R3 – 30 kOhm;
• R6 – 150 Ohm;
• R7 – 470 Ohm;
• R8-R10 – 43 Ohm;
• C1, C2, C4 – 150 pF;
• C3 – 0.01 µF;
• VT1 – VT2 – KT399A;

Choke L1 is a frameless coil wound with PEV-2 wire with a cross-section of 0.4 mm, the diameter of the coil is five millimeters, there are 4 or 5 turns.

You can use batteries to power the circuit, but it is better to take a power supply for this. In the latter case, the transformer may create interference, so it is advisable to place the power supply in a separate housing. That is why it is advisable to install the splitter in a wireless zone, that is, where there is no electrical wiring.

Note that the above antenna splitter circuits have proven themselves to be effective in dividing analog signals; as for satellite and digital television, it is better for them to buy a ready-made device than to make it yourself.

Price overview

As an example, we chose the Luxmann SP-202 splitter, which allows you to connect two TVs to one antenna cable.

As can be seen from the table, the price of an antenna splitter in Moscow, Krasnoyarsk, Minsk and other cities does not vary much. How economically profitable it is to make it yourself or buy it is up to you to decide.

What to consider when choosing a splitter for your TV

A TV splitter is a special antenna divider. They are used in cases where there is a large single TV in the room and the signal needs to be distributed consistently between different consumers. A television splitter with an amplifier can serve a large number of devices at once (from 3 and above).

And if we talk about such devices, in general, they are necessary for frequency separation of channels. And also such devices additionally have built-in protection against incorrect pulse voltages and currents that may arise in the cable cores during a thunderstorm. The splitter also protects against interference from power transmission lines and contact networks of electric vehicles.

What are there

The best splitters are those that include transformers with high resistance and higher frequency. But they are quite expensive and technologically weak. Typically, they are only able to split the signal in two directions. When you need more, a splitter with resistors in series would be a good solution.

There are television crabs with 2, 3, 4, 6 or 8 outputs under the F connector for general and satellite television. They are characterized by high throughput.

Popular TV splitters:

1. RTM type SAH 204F. 2-way splitter (isolation 28 dB, pass loss 3.6 dB).
2. TLC type SAH 306F. Directions - 3 (isolation 28 dB, transmission loss 5.8 dB).
3. Tbtec type HST 0408/F. 4-way splitter (isolation 32 dB, pass loss 7.2 dB).

The power division ratio can be equal (in most cases) or unequal.

How to choose

When choosing a television splitter, you must be guided by the following parameters:

• what frequency are the received channels;
• how many TVs are planned to be connected;
• cable cross-section by diameter;
• How experienced is the installer?

Action plan during the selection process:

1. Using the menu of your TV, you need to find out the frequency of all received channels. Having determined the channel with the highest frequency, you should make sure that the upper limit of the splitter’s range is greater than this indicator.
2. Count all available television devices, and also think about the prospects. Based on this, you need to choose a splitter with a number of outputs that exceeds the number of household appliances.
3. In addition, you should evaluate the attenuation of the splitter, the unit of measurement of which is decibels. This value can be found on the device body or in the included instructions. The lower this indicator, the more valuable the device is.
4. Appearance and dimensions. If the separator is in a visible place, it is important that it looks aesthetically pleasing. And if it is located inside the cable box, then it would be nice to pick up a small splitter.
5. How to pin. Of course, it is possible for it to simply hang on the wires. But it’s better to fix it on the surface - it will be more reliable and prettier. This means you need to check that it has holes for fastening.
6. There can be many connection methods. You need to focus on the type of cables used, as well as whether it is possible to solder.
7. When making a purchase, it is important not to confuse a splitter with a diplexer or coupler.

If you take these points into account, then no further problems should arise during operation.

How to connect

There are different connection methods:

• a splitter with a screw clamp can be combined with cables of any diameter and does not require soldering skills;
• a device with threaded connections is compatible only with thin cables, but also does not require soldering;
• a device with coaxial sockets can be connected to any cables using regular antenna plugs;
• splitters that require soldering.

And the connection technology itself includes several simple steps:

1. Decide on the appropriate surface and attach the separator to it.
2. Remove the plugs from each connector on the antenna splitter.
3. Using a coaxial cable, connect the input to the TV and the jack.
4. Connect a common TV cable.

The whole process takes about a quarter of an hour.

It is important, when buying a splitter “for growth” (perhaps more TVs will appear in the future), temporarily drown out the excess unused outputs with a resistor that will absorb excess voltage in the circuit (up to 75 Ohms).

When the image is no longer satisfactory

It happens that after introducing a splitter, the image quality on several TVs deteriorates. Some people get out of this situation by connecting a Polish antenna with an amplifier. And the second solution to the problem is to purchase a television splitter with an amplifier. The last method is good if before this the TV showed without any complaints and, in fact, there were no complaints about the antenna.

Quite often, one family has two or even 3 televisions, but there is still only one antenna. Many home craftsmen have a natural question: how to connect several TVs to one antenna, given that they are all located in different rooms. This can only be done using a special TV signal divider or splitter.

In strict technical language, this is a device that consists of a set of resistances designed to match the wave reactance of antenna feeders and several television receivers. The splitter, in addition to a stable connection, guarantees support for the passing signal with minimal attenuation.

On sale you can choose a splitter for two TVs, and if you need to connect 3 TVs, then you need to choose splitter with three outputs.

Advice! When using a 3-output splitter, you need to connect three TVs; if there are fewer, then a 75 Ohm ballast resistor is connected to the free port, which ensures normal operation of the splitter.

When choosing such a device in a store, first of all, find out from the seller the frequency range that it passes, so that when installing the line on 3 TVs, there will be no problems with the signal. Detailed information is also available in the device's operating instructions.

Crab splitter

The design of the splitter (its popular name is CRAB) is enclosed in a durable body made of brass or silumin(90% aluminum and 10% silicon), which is not subject to corrosion, but is much lighter than stainless steel. On the outside there are connectors for connecting F-plugs: on one side for an antenna, and on the other two or more - this is for connecting TVs. Its circuit is quite simple, usually transformer-based: one turn of enamel-coated wire with a cross-section of no more than 0.4 mm, which is threaded into rings or ferrite tubes. The case is closed with a lid, which is sealed or fixed with high-strength glue to enhance the tightness.

How long do we connect TV?

Before making the connection and final assembly of the entire line, you need to specifically determine the number of connected TVs. How to connect two TVs to a satellite dish is one question, but if you need 3, then the circuit will be slightly different and the splitter will be used with three outputs. In addition, it is necessary to take into account signal attenuation, which increases as receivers become larger:

• 1 TV - signal power is 1/1;
• two - signal 1/2;
• 3 - power is only 1/3.

Therefore, when installing a line on three or more TVs, a signal amplifier is installed. Specialty stores offer a wide selection of such products with characteristics that allow you to make a connection without loss of image quality.

Assembling the connection diagram

Consider the option of connecting two TVs, one of which is in the living room, and the second in the children's room. We will use an antenna splitter or splitter that splits the main signal into 2 TVs. Modern equipment is used to carry out the work, so we do not need a soldering iron, tin or rosin.

The new type of splitters use screw sockets: a pre-stripped one end of the cable is inserted into the nut, and the second with a similar plug will subsequently be connected to the TV. The central core must be inserted into a special hole in the splitter screw socket, and the nut is screwed on and tightly presses the copper braid of the cable to the device body.

Before starting work, you should disconnect the products from the network until all work on connecting TVs to one satellite dish is completed.

Step-by-step instruction:

The figure shows the connection diagram for a) 2 TVs and b) an option for 3 TVs.

How to boost the signal

Many users complain that when they connected two TVs to one antenna (satellite or simple), the image became much worse. There is nothing unusual about this - the fact is that the splitter only divides the signal. To eliminate such a negative phenomenon, you need to use a special tv amplifier, which is designed almost similarly to the crab, but there are resistors and a microcircuit.

It requires separate power, so when installing it, you need to have an outlet or a carrying case nearby.

TV amplifier

It is better to install the amplifier as close to the antenna as possible, and make branches from it: for example, in our case, one branch goes to the living room, and the other to the children's room. In this case, experts advise not to use a splitter, but to install an amplifier - it will cost more, but the signal quality will be high.

There is another option to get rid of interference (and you can also significantly improve the signal quality) - put special cables on the cable connecting to TVs ferrite rings. This can be done on the part of the cable that is not visible from the side, next to the connection to the antenna input on the TV. Such noise suppressors are installed, for example, on the laptop adapter cable - a small cylindrical device on the cord next to the plug connecting the cord to the computer. There are other ways. Also, do not forget that the quality of the signal depends on the antenna itself, so it is worth knowing. If you have the skills to work with soldering equipment, then you can even make a high-quality one. And then you won't have to think why your .

TV crab(splitter, combiner, splitter) is a radio device designed to connect several receiving devices (TVs, video recorders) to one or more television signal sources (cable network, ordinary or satellite antenna).

I came across a homemade splitter that I made when the first VCRs appeared, and it became necessary to watch one program on TV and simultaneously record another. Back then the word crab was not used, and such devices were called “TV signal splitters.”

The design of the splitter is a flat box with four threaded axle boxes riveted at the corners. The top of the box is closed with a lid made of a sheet of foil fiberglass with four screws. The cover can be made of any metal, iron, brass, thus ensuring shielding of the splitter parts.

Three standard old-type television connectors are secured to the cover using M2.5 screws and nuts. The radial leads of the connectors are soldered directly to the cover. Thus, they are connected to each other and electrical contact with the screen is ensured.

The splitter parts are mounted directly on the central terminals of the television connectors.

Although more than a dozen years have passed since then, the electrical circuit diagram of the splitter has not changed and all modern television crabs and splitters are made according to the same electrical circuit. The photo shows a schematic diagram of a splitter for connecting two TVs.

To match the central outputs of connectors XW2 and XW3, a 150 Ohm resistor is installed. Transformer T1 can be made independently by winding a wire with a diameter of 0.2-0.3 mm evenly in a circle in two wires on a ferrite ring with a permeability of 600-2000 with an outer diameter of 7-10 mm. When wiring the transformer terminals, the phasing must be observed; the beginning of the windings is indicated by a dot.

I still sometimes use this splitter when I need to connect two TVs standing next to each other to compare picture quality or settings.

Although the crab has Soviet-made sockets installed, you can connect both Soviet-made plugs and modern F-connectors to it. When making a television splitter yourself, you can install modern television F-connectors instead of obsolete connectors.

How to make a TV crab from scrap material

You may have wondered and wondered what a metal box of candy is doing on a page about making your own TV crab.

Yes, this is indeed a box of lollipops, but they are no longer there, since a home-made television crab is made from it, its technical parameters are not inferior to any other industrially produced ones.

If you open the lid and look into the box, everything will immediately become clear. This is a homemade television crab, made according to the above electrical circuit diagram, but instead of connectors, the wire connections are made by soldering.

This design of the crab is completely justified; the television crab is a stationary device, it is installed once and in the future there is no need to change its installation location. And most importantly, such a TV crab can be made from any metal shoebox, sweets, or coffee. The size does not matter, the main thing is that the antenna cable mounting brackets and several radio elements fit.

To make a television crab, you need to make holes in the box at the bottom level for the television cable and in the bottom of the box for mounting brackets. If the walls of the box are thin, then it is better not to drill holes, but to push them through. First pierce it with an awl, then insert the tip of a small screwdriver into the resulting hole and press down while rotating. The hole will get larger. By changing the size of the tool, bring the diameter of the hole to the outer diameter of the television cable. The clamping strips can be made from any metal. The good thing about a pressed hole is that there are no sharp edges that can cut through the cable.

After preparing the box and clamping strips, you need to cut the television cable. It is very important not to cut the central core when removing the insulation. There is no need to remove the cable shielding, but wrap it in place with a strap.

Now you need to insert the prepared ends of the television cable into the holes of the box and secure them with clamping strips. Bend the stripped ends of the central core of the cable slightly upward.

All that remains is to mount the transformer and resistor, close the lid and the TV crab will be ready for use. If the box is of small depth, then you need to make sure that the exposed parts of the parts and the central core of the cable do not come into contact with the cover.

If it is not possible to get a ferrite ring to make a transformer for a television crab, then instead of it a splitter can be made using resistors according to the electrical circuit diagram below.

All resistors of the splitter have the same resistance, which, depending on the number of televisions connected to the antenna wire, is calculated using the given formula.

For example, to connect three TVs to a TV crab, the resistance value R will be equal to 75 Ohms × (3−1)/(3+1)=37.5 Ohms. From the standard series, the resistor with the closest nominal value is 36 Ohm, and that’s what you should take.

Below is an online calculator with which you can calculate the value of resistors for a crab, depending on the number of planned televisions or other television signal receivers for connection.

The resistor value for making crab is taken from the standard range closest to the calculated value.

The most reliable type of connection of radio components is, of course, soldering. But if it is not possible to perform the connection work in a television crab by soldering, then you can get by by twisting the leads.

For reliable contact, it is enough to tightly wrap the resistor terminal with three to five turns around the central core of the television cable. The contact will not be as reliable as with soldering, but it will be quite sufficient for stable operation of the TV crab.

You can also use a plastic box as a body for a homemade crab if you cover its body and lid from the inside with staniol (aluminum) foil. A prerequisite for this is to ensure electrical contact between the foil of the housing and the cover and with the shielding braids of the television cables.

For reliable contact of the braids, before clamping them with clamping strips, you need to wind several turns of a piece of any copper wire onto each one.

How to make a TV splitter from three resistors

For the case when there are no materials at hand, and only a knife is the only tool, I present the simplest version of a television signal splitter, with only three resistors. To your surprise, in terms of technical characteristics, if carefully executed, despite its simplicity, a homemade television signal splitter of this design will not be inferior to branded samples.

Using the technology previously described, the insulation is removed from the ends of each television cable that will be involved in the manufacture of the splitter. The cable must be cut as in the photo. I had to cut off the outer insulation completely, since I came across a Soviet RK-75 cable with very hard insulation. If the insulation is elastic, then it is better to cut it lengthwise and bend it back in order to return it to its place after soldering the resistors, as in the cutting examples when extending a television cable. The central core of each cable is tinned with solder and a resistor lead, bent into a loop, is put on it.

Now just a drop of solder from the soldering iron is enough and you get reliable contact and a strong connection. For ease of operation, the cables that will go to the TVs are laid parallel to each other and wrapped with several turns of insulating tape.

Then the shielding windings of all cables are soldered together. After this, the lead of one of the resistors is formed into a loop, the leads of the other two are threaded into it and soldered together with a drop of solder with a soldering iron.

If the outer sheath of the cable has been bent, it is returned to its place, thus isolating the resistors. In my case, I had to take a piece of insulating tube, cut it lengthwise and close the junction of the resistors. Thick insulation in this case is needed in order to ensure the minimum permissible distance between the central core of the cable, resistors and the screen. The cambric is fixed with a turn of electrical tape so that the cable braid remains open on both sides.

Next, the installation location of the TV splitter resistors is shielded. To do this, you need to wrap it around stranded copper wires turn to turn. You can simply wrap it in aluminum foil and then wrap it around a few turns of wire, as in the photo. The main thing here is that the screen has electrical contact with the shielding braid of the television cable.

Finally, the splitter is covered with several layers of electrical tape to give it an aesthetic appearance. To impart rigidity and strength, it is advisable to place a metal strip along the television cable before insulation, but it can be made of any material.

The end result was a splitter as good as any crab. The disadvantage of this design is the inability to quickly switch the antenna cable.

Resistor values, depending on the number of connected TVs, are calculated using the formula given on the page above. Instead of resistors, it is better to use a transformer, then there will be less loss of the television signal.

This is wrong, but in a hopeless situation it is permissible to connect the central core of the antenna cable with cables going to the TVs directly to each other, without resistors or a transformer. Since the cables will not be matched in terms of characteristic impedance, you will have to pay for such a splitter by losing the quality of watching TV shows. There may be interference from the local oscillator of a TV connected in parallel (only when both TVs are working simultaneously) and a small fringing in the image. This connection is safe for both televisions and cable equipment or a television antenna.

To build a branched structure of television lines and form a coordinated signal distribution between subscribers, a TV splitter is used. Its choice is based on a number of factors and depends on:

• operating frequency range
• number of outputs for connecting multiple TVs
• cable attenuation values, etc.

4 rules for choosing a suitable TV signal splitter

1. To divide the broadcast signal, it is enough to select a TV signal splitter operating in the range of 5 – 1000 MHz. If you need to branch out from a satellite head, then you need a device for the range 5 – 2500 MHz, preferably with a power pass function. It will allow direct current to be passed through the television splitter to power the head, which is controlled by the satellite tuner.

2. The main task for the user is to receive an equally good signal on all receiving devices. Dividing the signal involves a relative decrease in decibels at the next tap. When dividing by 2 TVs, the input signal level will decrease by 3 dB, for 3 TVs - by 6 dB, etc. As a result, it can reach such low levels that it will not be enough for normal intake.
The solution lies in the TV splitter amplifier. To improve reception quality, it has sufficient dynamic range, good sensitivity and low self-noise.

3. The attenuation value is displayed in the technical specifications of each TV cable splitter and is expressed in dB. The best device will be the one in which this indicator is lower.

4. To divide the signal multiple times when connecting a large number of subscribers, you will need an active TV splitter that will operate without loss and transmit weak signals with the necessary amplification.

It’s difficult to surprise anyone with two TVs in an apartment these days. Technologies, and even the signal receiving devices themselves, are constantly developing in our fast-paced age, which inevitably affects the reduction in prices for older models. And this, in turn, leads to the fact that almost every family can afford a second TV, or even a third. Agree, it’s still convenient when you can watch your favorite programs in the kitchen or in your room without disturbing any of your family members. And in this case, we will definitely need an antenna splitter.

Active or passive: how to make the right choice?

Don't even think about simply connecting a couple of wires in parallel to the antenna and thus getting another signal source. The picture quality as a result of such an operation will be very poor - multi-contours will appear, contrast will decrease, etc. That’s why you need to use an antenna splitter, or, as it is popularly called, a “crab.”

If the signal source is good, which can be determined visually, and before that there was only one TV in the house, then a model assembled on the basis of resistive dividers is quite suitable. Such an antenna splitter is considered passive and, although it provides good signal matching, it still introduces a certain attenuation, proportional in strength to the number of outputs. This type has proven itself well in a large city or nearby metropolis, where the broadcast power is quite high.

Accordingly, if reception is poor or there are a large number of receivers, it will be better to use an active type antenna splitter. Such a device not only separates the incoming TV signal, but also amplifies its power.

When purchasing a splitter, pay attention to the attenuation level, which is indicated in decibels both on the device label itself and in the accompanying instructions. The lower the value of this indicator, the better. If you can see the frequencies of received channels in the TV menu, then remember the highest value and check that it is included in the selected device.

How to connect an antenna splitter

All you need to connect a second TV besides the device itself are mounting brackets (if the cable will be attached to the wall), a sharp knife, a regular tape measure and antenna plugs (according to the number of additional TVs). First, we select a place in the apartment where the antenna splitter will be placed. It is best to use special sockets mounted on the wall of the room for this purpose. Then we measure the number of meters from this point to each of the two TVs, add them up, add a couple of meters for reserve and buy the required length. Now it needs to be cut into the required pieces, from the ends of which the outer shell is removed with a knife, and the braid is bent outward onto the uncleaned part.

After this, instead of the plug, which is located at the end of the old one, a splitter for the antenna is connected, and to it - pre-prepared pieces of cables for all television receivers. Then all these wires are fixed motionless using staples or a plinth cable channel. The last thing left to do is to turn on all the devices and check the quality of the received signal.
