Connecting one digital set-top box to two TVs. How to connect two TVs to one antenna? Is it possible to connect 2 TVs to cable

TV has long been considered an attribute of luxury, so every second family has at least one or two such devices. If the first device is located in the bedroom, then the second one can stand anywhere, for example, in the hallway, living room, kitchen or any other room. Owners of several devices sometimes need to connect two TVs from one antenna.

general information

Trying to figure out how to connect 2 TVs from one antenna, you need to deal with general principle such a procedure, the required tools, and the milestones. To connect devices, you need to use several available tools and parts. Among them:

pliers;
side cutters;
kitchen knife.

The first step is to purchase a TV splitter or splitter that can split the antenna signal into two streams. On one side there is an input, and on the other side there are outputs for connecting to the receiver.

After that, you need to take 5 connectors that match in thickness with the outputs on the splitter, as well as adapter plugs. When choosing an antenna cable, it is recommended to give preference to high-quality and proven models, for example, RG-6 or PK-75.

When choosing a splitter or splitter, it is important to consider the number of outputs, because three-way models are intended for the interaction of three devices, but not two. If such an option was purchased, but there are only two TVs in the house, it can be closed with a special resistor with a resistance of 75 ohms. In this case, you need to read the step-by-step instructions on how to connect 2 TVs to one antenna.

The connection procedure itself is not something complicated, so even an inexperienced user who does not have any radio technical skills will be able to carry out such manipulations without outside help.

Splitter types

The main purpose of the splitters is to match the wave impedances, fix a stable signal, as well as combat all sorts of noise and interference. A properly selected splitter guarantees high picture quality and prevents any distortion. But in order to make the right decision at the selection stage, you need to know what types of such devices are, what they are intended for and what properties they have. There are two main types of splitters available on the market:

with an active form of work;
passive.

Such devices may have one input and a pair of outputs. In most cases, models with two or three outputs are used for home TVs, although their number is not limited. Splitters evenly distribute the signal from one antenna, so if the input signal intensity is 12 dB, then the TVs will receive half of this value, that is, 6 dB each. If the crab for the antenna is equipped with three outputs, then the received TV signal will be 4 dB. Passive models may use transistors or transformers.

As already mentioned, the number of outputs in the splitters can vary from two to eight. When it comes to buying a model for two TVs, it is better to make sure that in the future you will not have to connect several more receivers to the same antenna. It is also important to consider the level of attenuation that the splitter has, because the lower it is, the better the image quality.

Splitters with a built-in RF amplifier belong to the active group. They are able to capture a high-quality signal and raise it if necessary. But for the operation of such a device, it is necessary to use power. It can be a separate unit or a cable connection.

Device selection

If you are interested in how to connect two TVs to one antenna, you must first purchase a splitter. There are a lot of such products on sale, so there will be no difficulties in choosing the right model. In this case, the principle is appropriate: the more expensive, the better.

At the stage of purchase, it is important to take into account your skills in working with a soldering iron. If they are present, then you can buy a soldered splitter, since it is characterized by noticeably less signal loss and the ability to maintain transmission quality.

If you didn’t have to work with soldering tools, it’s better to opt for a regular splitter. However, in this case, it is necessary to pay attention to the type of cable that the device is equipped with. The best option is a splitter with a standard connector for coaxial wires.

Having decided on the choice, it remains to find suitable connectors. In most cases, a convenient F-interface is used for this purpose, which is a wrap adapter.

Besides, it is important to choose a suitable location for the splitter keeping the correct distance between it and the TVs. Experts recommend choosing an approximately equal distance, while the cable for the antenna should not be twisted and stretched. You can not stretch it with a lack of footage or, conversely, twist it excessively. It is important to pre-calculate the distance between the splitter and the TV, as well as get rid of the excess.

At the stage of preparing the cable, you need to cut it so that it freely reaches the splitter. Together with the remaining piece of wire, the old plug must also be cut off. After that, you should cut the cable for mounting in the F-connector.

First of all, it is necessary to cut the wrapper to the braid (about 15 millimeters from the edge), and also bend the edges. The insulation layer should protrude slightly, and the core end should protrude by 4-7 mm. You need to prepare the cable for the adapter-plug with a kitchen knife and side cutters.

Features of the procedure

When figuring out how to connect multiple TVs to one antenna, you need to follow the step-by-step guide. To successfully complete the task, the following rules must be observed:

In the correct order, it is necessary to connect the cables to the splitter, while not overtightening the F-connector, as this may cause the main core to fall out of the adapter. Many people do not change the location of the splitter, leaving it somewhere under the furniture or near the baseboard. Experts advise to securely fix the splitter, otherwise it may be damaged by contact with children or pets. The splitter can be hidden behind any false panel.

If follow step by step instructions and correctly perform each step, then a clear picture should appear on the TVs without interference or deviations. If something is done wrong, the so-called snow will appear on the screen, which indicates a partial loss of signal or a complete lack of image.

Satellite TV and Polish antennas

If any stage of the splitter installation is incorrectly performed, image quality may be lost. A similar phenomenon often appears when working with a satellite dish, when the splitter takes part of the signal onto itself.

To eliminate an unpleasant problem, you need to purchase a splitter with a built-in amplifier. Its cost may differ significantly from the price of conventional models, but this is justified by maximum efficiency. In addition, all amplified splitters support different gains, because under some circumstances a strong signal becomes just as unnecessary as a weak one. And given the fact that sometimes it even aggravates the problem, it is better to abandon this option.

If a classic Polish antenna is installed in the room, then in order to improve the signal, you can connect an amplifier with a power supply. This will make the picture quality and prevent snow from appearing on the screen. . To solve the problem, you must follow the following rules:

According to the familiar scheme, it is necessary to make several changes to the amplifier.
You should remove the F-type connector from the input, and install the plug that comes with the antenna in the place that appears.
Next, you need to install the adapter with the antenna socket and connect the amplifier.

By performing such measures, you can significantly increase the gain. To permanently get rid of the poor picture quality on two TVs, it is better to buy two antennas at once.

Ways to amplify the signal

For many TV owners, after connecting several TVs to one antenna, the quality of the displayed picture deteriorates greatly. This is due to the principle of the splitter, which only splits the signal into several streams. To eliminate the negative phenomenon, it is necessary to purchase a special amplifier that works on the principle of a crab, but has several resistors and an amplifying microcircuit.

For such a device, it is necessary to equip a separate power supply, so when performing installation work, you need to consider the location of the outlet or extension cord. It is recommended to install the amplifier at a short distance from the antenna, and make branches from it to the desired part of the room. Experts argue that it is much wiser to abandon the splitter and give preference to amplifiers. Such a purchase will be more expensive, but it will be justified. high quality transmitted signal.

To prevent all kinds of interference on the screen and improve the signal, special ferrite rings can be placed on the television cable. They are placed at the very end of the cable near the antenna input. Similar interference cutters are present on the cords of laptop power supplies and are intended to combat poor signal transmission quality.

There are other less effective ways amplifying the television signal, but a lot depends on the antenna itself. In order not to think about how to get rid of the problem of poor picture quality when connecting several TVs to one antenna, it is better to buy a good device in advance and prevent such troubles.

The process of amplifying the signal from the antenna to two TVs is carried out through the interaction of two devices - a preamplifier and a distribution amplifier. According to the principle of operation, these nodes practically do not differ from each other, but some differences are still present. The preamplifier is located on the antenna and is designed to amplify the signal. It is used for a long coaxial cable and is fixed between the antenna and the splitter.

The amplifying device is mounted in front of the splitter and used to amplify the split signal, for example, for two or four TVs. Most amplifiers work exactly like splitters, so it makes sense to choose one and not buy a splitter.

Connecting two, three or more TVs to the same antenna is not a difficult task. Even an inexperienced beginner who does not have professional skills can carry out such a manipulation and achieve good results. The main thing is to follow the step-by-step instructions and take into account the recommendations of experienced professionals.

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

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

Each of them serves to solve certain problems.

Purpose and main differences

Splitters allow you to evenly split the TV signal between multiple 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 - 4 dB, a quadruple - 3 dB.

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

A - signal input;

B and C - exit.

Antenna splitters of this type are used in cases where it is necessary to send a signal to 2 or 3 TVs, and more if the device is with 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, they can play the role of an adder or a divider.

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

A and B are input signals;

C is the output signal.

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

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

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

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

A - incoming signal;
B, C, D, E, F, G, H, I, J - tapping signals (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 fed to the input connector of the next coupler.

Video: TV antenna splitter.

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

In everyday life, it is splitters that are most often used, they serve to connect several TV sets 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 borne in mind that the operating frequency of antenna splitters for digital television and satellite dishes are different. For the former, it is limited to 1 GHz, for the latter, 2.5 GHz. In addition, the satellite splitter may have a “Powerpass” function (allows you to supply power to the head of the satellite dish).

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 case, the lower it is, the less loss.

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

How to connect

The instructions for connecting the splitter are quite simple:

choose a place and fix the divider on it;
then you need to remove the cap 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 TV cable included in the apartment.

Do it yourself

It is not difficult to make a splitter for analog television with your own hands, here are a few simple circuits such a device.

Passive splitter with resistors.

The figure shows two schemes:

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 the PCB layout for circuit "b".

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

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

Schematic of an active splitter.

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

Parameters of the elements indicated in the diagram:

R1-10 ohm;
R2, R4, R5 - 430 ohms;
R3 - 30 kOhm;
R6 - 150 Ohm;
R7 - 470 Ohm;
R8-R10 - 43 ohms;
C1, C2, C4 - 150 pF;
C3 - 0.01 uF;
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, turns are made 4 or 5.

Batteries can be used to power the circuit, but it is better to take a PSU for this. In the latter case, the transformer can interfere, so it is advisable to place the power supply in a separate case. That is why it is desirable to install the splitter in the wireless zone, that is, where there is no electrical wiring.

Note that the above antenna splitter circuits have proven themselves well in dividing the analog signal, 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, a Luxmann SP-202 splitter was chosen, which allows you to connect two TVs to one antenna cable.

City	Cost (USD)	City	Cost (USD)
Yekaterinburg	4	Penza	4,2
Krasnoyarsk	4,1	Minsk	4,1
Moscow	3,8	SPb (Petersburg)	3,85

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

Dear visitors!!!

Many of us need to connect two TVs to one TV cable. For example, doing our own business in the kitchen, or relaxing in the hall, we can watch one or another television channel and be aware of all the events taking place in the world. This opportunity is provided to us when connecting a television cable through a television signal divider.

TV signal divider

Connecting two TVs to one cable is done through a TV signal divider. When purchasing a signal divider, the diagram of such a connection is given on the case itself. So, how to connect two TVs to one cable from one antenna. Let's start with the TV cable itself.

TV cable connection

You need to first decide where you will have a cut of the television cable for further connection two television cables to a television signal divider. You will get one common TV cable that receives a signal from a TV antenna, connected to the TV signal divider jack.

How to connect a plug-in TV cable

In addition, another TV plug must be available. To solder the TV plug, you need:

remove a small part of the cable insulation;
unweave the outer braid cable;
twist the braid and pickle with soldering flux;
solder the outer braid to the outer pin of the plug.

The inner wire of the television cable, after wetting it with soldering flux, is soldered to the inner contact of the plug.

The connection of television cables with a television signal divider is carried out with the initial removal of a piece of cable insulation.

Now, let's get acquainted with the scheme of connecting two TVs - to one antenna.

Scheme for connecting two TVs to one antenna

Shown here are connections from one shared TV cable:

for two TVs
for three TVs.

The signal from the TV antenna is distributed through the TV signal divider and fed through the cable to the TV jack.

You should not focus your attention on connecting through a TV signal divider. The second connection option looks through the junction box.

Junction box

In this embodiment, a way to connect two TVs is clearly shown, where the cable wires can be connected in a junction box. The connected contacts of the signal wires of the television cable are etched and soldered with a soldering tin. Connecting two television cables to a common cable is parallel. There is nothing complicated here, as you have seen.

That's all for now. Follow the rubric.

Hello. I have such a question, two TVs are connected to one antenna through a divider, they showed normally, yesterday one was removed, today some channels were charged. Is there a relationship in this? Thanks in advance!

Hello! Is it necessary to connect through a splitter or a box? Just to get tied to the wire, I understand how? When 2 TVs are on, terrible interference is created

Hello. I connected the divider, but no result. In the wire from the antenna, and in the out wire from the TV. True, the power supply is connected to the TV and from the TV the wire went to the divider.

Hello. As I understand you, you have purchased an antenna with a built-in amplifier and a power supply. Connecting two TVs for your example looks different. The power supply must have two outputs to connect two TVs.
- Hello. Previously, an antenna with an amplifier was always connected through a separator. There was a loss of quality, but tolerable. Now terrible interference is being created. The first channel does not show at all. Only Russia 1 is good. Changed the splitters, the result is almost the same. Nowhere have I seen a power supply for 2 TVs. Do you need it yourself or can you make it?
  
  I understand that in this case, two TVs need two power supplies (connected to plugs)?

Victor good afternoon! Please help me with this question. At one time, during the repair, electricians made 3 points for a TV antenna for me (kitchen and 2 rooms). The wires were brought out under the floor into a soldered box, and there they were twisted into one wire and brought to the shield. How in my case to connect 2 TVs under satellite TV?

we have cables going to two TVs from the splitter, I need to connect a third TV, the question is - do I need a splitter for three outputs or put a splitter for two cables on one of the cables ??

Satellite TV on 2 TVs can be connected in different ways - using a second tuner (receiver), using an RF module, etc.

One set of equipment for connecting to satellite TV is designed to connect only one TV. Therefore, to connect two or more TVs, additional elements or another set of equipment are required.

Receivers for connecting two TVs

If one of the devices has not only an input, but also an output jack for the antenna (not to be confused with the modulator jack - it is designed to connect the device to a TV at high frequency), then you can connect a cable to this jack, which is designed to connect satellite dishes to receivers . Connect the other end of the cable to the input socket of the second receiver. You will get a serial connection of the converter and two receivers. If you receive encrypted channels, you will have to purchase a separate card for each receiver and pay a subscription fee. In addition, with such a connection, it will not be possible to watch channels with vertical polarization on one receiver, and with horizontal polarization on the other.

With this connection, the slave (second) receiver must be configured so that the “Power” option is disabled. Otherwise, problems may occur when watching channels.

It makes sense to use this connection option when the user wants to use one TV, for example, only for watching paid channels, and the other for free ones.

You can use a splitter that is designed for satellite receivers and converters. This connection method will have the same disadvantages as the previous one. Additional equipment must be used if none of the receivers has an output jack for connecting a second device.

Installation on the antenna of 2 converters

If you install 2 converters (“heads”) on the antenna, you can connect them to two different receivers. They will work independently of each other.

But there is such a drawback: 2 converters cannot be directed to one satellite. You will have to watch different channel packages from different satellites. If the channels are encrypted, you will have to purchase 2 cards and pay 2 subscription fees.

Installing a converter with two outputs

Another option is a converter with two outputs. One of them can receive channels with vertical polarization, the other - with horizontal polarization. Both outputs need to be connected to a multiswitch, and parallel cables to TVs should be pulled from it. On any of them it will be possible to watch channels that are broadcast in any polarization. All required switching will automatically be done by the multiswitch. But for each receiver you will need a separate card and a subscription fee.

If you want to use one receiver and one card, and the receiver has a high-frequency modulator, then you need to connect the modulator output to two TVs through a splitter that is designed for terrestrial antennas. Both TVs need to be tuned to the satellite TV channel that the modulator broadcasts. When you change the channel on the receiver, it will change simultaneously on both TVs.

You can connect one TV at a low frequency (for this you need RCA or SCART connectors), and the second at a high frequency (for example, through a modulator). The result will be the same, but with this connection, it will be possible to connect a regular indoor or outdoor antenna to the first TV, and independently receive on-air channels. And if one TV is connected via RCA, and the second via SCART, then it will be possible to watch channels from a conventional antenna on both TVs.

You can connect satellite TV to two TVs and through one receiver. In this case, the first device is connected to the first TV using a “tulip”, and the RF module is connected to the second output on the tuner, which is designed to connect other monitors.

This method has many disadvantages. You can change channels only in the room where the receiver is located. And the main drawback is that both TV sets show the same channel.

Setting the divider

There is an option to use a splitter or splitter. These parts divide the signal from the antenna into 2.

This branching option has screw sockets. One end of the cable is stripped, inserted into the nut, the second with a similar plug is connected to the TV. For the central antenna cable there is a special hole for the splitter screw socket. It is necessary to insert the end of the cable there, and tighten the nut, and firmly press the copper sheath to the body of the device.

The procedure for connecting a satellite dish to two TVs is different for each model.

Instruction

Purchase a special cable of the appropriate length, as well as a splitter with two outputs. The image quality will depend on the cable.

If one TV is already connected to the antenna, then the end of the cable must be removed from the TV and inserted into the output port on the separator, tightening the nut tightly.

Cut off the small end of the cable from the common coil, put standard plugs (heads) on the ends, clamp them.

In the same way, connect the plugs to the large (remaining) piece of cable that will be used to connect the channel splitter and the second TV.

Plug all the plugs into the corresponding sockets on the body of the splinter and the TV.

Hide the cable that goes to the second TV under the baseboard or somewhere else so that it does not get under your feet. If possible, it is better to drill the wall to pull the cable to the second TV. This will make it possible to use a shorter cable length.

After connecting the antenna to two TVs, check the picture quality on both receivers. If the quality is not very good, then check the fastening of all plugs at the ends of the cable, tighten them harder.

Setting

Press the menu button.
Determine the desired source for the signal, select it.
In the selected source, mark the connector to which the TV is connected.
Start searching for programs.
After the search is completed, remove from the general list those channels that do not have a clear image.

The best option for connecting a satellite dish to several TVs

To watch different TV channels on 2 (3, 4, etc.) TVs, you need to connect a separate tuner to each of them. But such an elegant cable solution is very expensive in terms of money.

You will need 3 separate cables, from the converter ("antenna head") to each receiver - a separate cable. For this, there are special converters with a different number of outputs - 2, 4, 6, 8. Accordingly, if you want to connect satellite TV to 3 TVs, you will need a converter with 4 outputs.

Splitter

It is considered the most financially advantageous way to connect. The signal can be received from any satellite, but such a system will not always work acceptable.

Multi Output Converter (LNB)

There are several modifications of this element, each with a different number of outputs - 2, 4, 8, 16. Each TV needs a receiver, or the TV must have a built-in DVB-S2 tuner and a CI + slot for a CAM module. A separate cable is pulled from the converter to each TV.

There are C and Ku range convectors. All paid satellite TV operators operate in the Ku-band. Satellite Converter (LNB) Ku-band is divided into:

circular ("Tricolor-TB - Siberia", "HTB-Plus-East") polarization;
linear (“Continent-TV”, “Vostochny Express”) polarization.

This type of convector is considered the most reliable connection option with a minimum number of connections.

ST to multiple TVs

There is another option for connecting multiple TVs to multiple satellites. If it is necessary to connect a large number of subscribers to one antenna, then a special device is used for this - a multiswitch, which divides the signal into several convectors. Most often, this element is used to create a network with a large number of users (for example, in urban apartment buildings). If you need to connect CT to several TVs in a private cottage, then it is more convenient to use convectors with independent outputs.

CT from multiple satellites to multiple TVs

For this connection option, in addition to convectors with independent outlets, devices such as "diseks" ("dyseks") are also required. They are designed to receive a signal from different satellites over a single cable. Diseks are adapted for different protocols. The protocol standard for which a particular disc is intended is indicated on the packaging or on the device itself. For example, "DiSEqC 1.0 - up to 4 convectors". For the whole system to work, the receiver must also support the standard for which the disc is selected.

Special offer from "Tricolor-TV" - set for 2 TVs

This operator makes a unique offer to customers - a special set of equipment for two TVs. This is considered the best connection option, because. it is possible to satisfy the interests of all residents of one apartment without significant financial costs.

The most complete set, which will make it possible to connect everything without any hassle, includes:

an antenna ("dish") equipped with a converter with two outputs;
receiver GS E501, which combines the functions of two tuners (or another receiver model with similar capabilities);
prefix GS C-591;
2 remote controls and 2 power supplies;
access card;
cables for connecting equipment to the antenna;
"twisted pair" for connecting the set-top box to the receiver;
HDMI cables for connecting TVs to set-top boxes;
documents and instructions.

If you have a receiver with two tuners, you can purchase a prefix-client. It costs less than a regular receiver, but you will need to pay separately for the viewing service on two TVs. In addition, the operator offers to exchange existing equipment for a new one with an additional payment.

There is no need to install a double converter on the antenna instead of one head with one output. It will be enough to install an antenna divider near the receiver, where the coaxial cable fits.

Connection is simple

A smart card is inserted into the main receiver (CS E501), it is the only one in the sales package. The two coaxial cables coming from the two outputs of the LNB on the antenna are plugged into LNB IN #1 and #2 on the same unit.

The device acts as a server that is able to decrypt the signal and transmit it to the GS C-591 set-top box using a twisted pair cable. After that, it remains only to connect TVs with set-top boxes using HDMI cables, and you can start searching for channels.

You can set up both devices to adequately display the signal using the appropriate instructions, or use the tips on the video. If everything is done correctly and the operator's services are paid, then both TVs will show channels independently of each other.

The advantages of this connection option:

First, there is no need to install a second antenna.
Secondly, you do not need to buy a second receiver if you buy a prefix-client, which is cheaper.
Thirdly, connecting to one TV costs 1,500 rubles, and to two - 2,000. A system for two TVs costs 1,000 rubles cheaper.
