Under general concept 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.
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.
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 sharing adder and divider, where:
- A – television antenna;
- B – satellite dish;
- C – adder;
- D – socket with a built-in divider for connecting two television cables.
Tappers 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 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.
Video: TV antenna splitter.
Antenna splitters can also include a range blocker (stub), which is widely used by operators cable television to separate social and paid packages connections.
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 head 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 body; the lower it is, the lower the losses.
It is also important who the manufacturer of the device is. Products of such famous manufacturers like: 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 a few simple circuits such a device.
Passive splitter with resistors.
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 wiring printed circuit board for scheme "b".
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 low level incoming television signal, you can correct the situation using a divider that has broadband amplifier frequency The 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 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.
| City | Cost (USD) | City | Cost (USD) |
| Ekaterinburg | 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 vary much. How economically profitable it is to make it yourself or buy it is up to you to decide.
As a rule, one digital set-top box is designed to connect one TV. If there are several TVs and all of them do not support the DVB-T2 standard, a separate receiver should be connected to each TV. Despite the low cost of set-top boxes, many people want to minimize costs and use one set-top box for at least two TVs. This is possible, but with certain limitations:
- One of the TVs must have a digital HDMI input (old CRT TVs cannot have it).
- Both TVs will show the same image, viewing different digital channels in this case is not possible.
- Channels are switched on the remote control of the set-top box, and the remote control only works in the line of sight of the set-top box. That is, if you watch TV in one room and the set-top box is in another, you will need to go to the other room every time you change the channel.
A typical example of the use of such a scheme is when one person watches channels from digital set-top box alternately in different rooms, for example, in the room and in the kitchen, and does not need to constantly switch channels. However, with a good location of the rooms and good reflective surfaces, the signal from the remote control can “fly” to another room through an open door.
Connection diagram for DVB-T2 set-top box for two TVs
If the limitations listed above do not scare you, then you can connect the digital receiver according to the diagram shown in the figure. The first TV, with an HDMI input, is connected with an HDMI cable to the corresponding output of the set-top box. The second TV is connected to the set-top box using an RCA cable, which is usually called “tulips”.
If the distance is small, then you can use a ready-made RCA cable the required length (usually they are no more than 5 meters). If it is not possible to buy a ready-made cable, you can purchase RCA plugs and use a regular cable to transmit the signal. To transmit an image with stereo sound you will need three cables, for mono sound two will be enough. We recommend using the plugs shown in the illustration. They are reliable, easy to use and do not require any tool other than a knife for installation. Initially, an F-connector is installed on the cable, and then an RCA plug is screwed into it.
Of course, such a task will require an additional design, namely a splitter or a special digital signal divider. This is a special device intended for these purposes.
Cable or antenna splitter for 2 TVs
A splitter is a device consisting of a set of resistances that are designed to match, to be precise, the wave reactance of the antenna feeders and several television receivers at once. The splitter provides a stable connection, and it also guarantees a transmitted signal with the least attenuation. Today you can buy a television divider for two televisions (2TV), or even for three (3TV).
An antenna splitter for 2 TVs can be purchased at any specialized store. The design of the splitter itself, which is popularly called a crab, is enclosed in a durable brass or silumin housing. It is not afraid of corrosion, and is lighter than stainless steel. On the outside you can see the connections of F-plugs, for the antenna on one side, two or three on the other - for TVs. The circuitry of the splitter is quite simple, most often a transformer one. Typically one turn of wire is threaded through rings or ferrite tubes. The case itself is closed with a lid, which is fixed with very strong glue or sealed for tightness.
How to make the connection: antenna splitter for 3 TVs
When you use a splitter with 3 outputs (popularly called a tee), then 3 TVs need to be connected to it. That is, there should be no free exit. If there is one, then you need to connect a ballast resistor (75 Ohm) to the two occupied outputs. This must be done to ensure active work splitter.
You can consider the connection using the example of two TVs to one antenna, acting on the principle “from simple to complex.” Of course, when connected, the devices are disconnected from the network. And they will only connect when both TVs are connected to the cable.
Buy a special coaxial cable with a length of at least 12 m, as well as a splitter with two outputs;
When the antenna is connected to both TVs, you need to check whether you are satisfied with the picture quality. If there are any distortions, you need to check the connections; you may need to redo the cable crimp. Usually a graphic diagram puts everything in its place: it shows how to connect two TVs at once, and how to connect three.
Amplifier antennas: how to connect a second TV to cable TV
An active antenna is one that has an amplifier that needs power. If such an amplifier is used, the supply voltage to it should not be interrupted. Then the connection diagram will be slightly different. The divider in it is ordinary, but the task is this: power needs to be supplied to the antenna, only this is done at the cable gap between the antenna itself and the divider.
Will need special element with a needle and thread on one side, and this connector is screwed into the input of the divider. The other side of this connector will be the antenna socket; connect the power supply separator there. It turns out that the antenna is provided with power even with a conventional divider.
Signal boosting: how to connect multiple TVs to cable TV
How many posts on thematic forums are devoted to the same topic - two TVs are connected to one antenna, and this affects the image quality. What's the matter? There is nothing surprising, since the splitter only divides the signal. To ensure clear image quality, use a special television amplifier. It is designed almost like a crab adapter, only with resistors and a microcircuit.
The cable splitter is inexpensive, so everyone can afford it How else can you get rid of interference:
- You can put special ferrite rings on the connection cable - this is done on the non-visible part of the cable, next to the antenna input connection to the TV;
- Similar noise cutters are found on the laptop adapter wire - this is a cylinder-like device on the cord, next to the plug where the cord connects to the computer;
- Well, remember that the quality of the signal depends on the antenna itself - therefore it is very important to choose the right antenna.
When choosing a splitter in a store, ask your consultant about the frequency range it allows. Otherwise, when installing on three TVs at once, problems with the signal may arise. When installing on three TVs, it is necessary to install an amplifier.
Today, fortunately, there are many similar devices in stores that allow you to install cable TV in literally every room. If there are two of them, then it’s two, or even more! Then the family will not quarrel among themselves about who should watch what. You can simply, relatively speaking, divide the TV into TVs - mom watches a cooking show, daughter watches a channel with Polish music, and dad watches sports competitions.
As you can see, there is nothing complicated. You buy a splitter, insert everything according to the instructions, and check the signal. Even a technology novice can handle this.
Satellite TV can be connected to 2 TVs different ways— using a second tuner (receiver), using an RF module, etc.
One set of equipment for connecting to satellite television 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 socket for an antenna (not to be confused with a modulator socket - it is designed to connect the device to a TV via high frequency), then you can connect a cable to this socket, which is designed to connect satellite antennas to receivers . Connect the second end of the cable to the input jack 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 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 arise when viewing channels.
This connection option makes sense when the user wants to use one TV, for example, only for watching paid channels, and the other is 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 of 2 converters on the antenna
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 should be drawn from it to the TVs. On any of them you can watch channels that are broadcast in any polarization. All required switchings will be automatically made by the multiswitch. But for each receiver you will need a separate card and subscription fee.
If you want to use one receiver and one card, and the receiver has a modulator high frequency, then you need to connect the modulator output to two TVs through a splitter, which 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 simultaneously change on both TVs.
You can connect one TV at a low frequency (for this you will 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, you can connect a regular indoor or outdoor antenna to the first TV and independently receive over-the-air channels. And if one TV is connected via RCA, and the second – via SCART, then you can watch channels from a regular 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 intended for connecting other monitors.
This method has many disadvantages. You can only change channels in the room where the receiver is located. And the main drawback is that both TV receivers show the same channel.
Divider installation
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 central antenna cable There is a special hole for the splitter screw socket. You need to insert the end of the cable there, tighten the nut, and press the copper sheath tightly against the body of the device.
The procedure for connecting a satellite dish to two TVs is different for each model.
Instructions
Purchase a special cable of 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 a small end of the cable from the common skein, put standard plugs (heads) on the ends, and 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 connectors 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 underfoot. If possible, it is better to drill into the wall to run 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 image quality on both receivers. If the quality is not very good, then check the fastening of all plugs at the ends of the cable and tighten them tighter.
Settings
- 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 completing the search, 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.
You will need 3 separate cables, from the converter (“antenna head”) to each receiver - a separate cable. For this, there are special converters with different numbers 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 profitable way to connect. The signal can be received from any satellite, but such a system will not always work acceptable.
Multiple 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 the CAM module. A separate cable is pulled from the converter to each TV.
There are convectors of the C and Ku ranges. All paid operators satellite television operate in the Ku-band. Ku-band satellite converter (LNB) is divided into:
- circular (“Tricolor-TB - Siberia”, “HTB-Plus-Vostok”) polarization;
- linear (“Continent-TV”, “Orient Express”) polarization.
This type of convector is considered the most reliable connection option with a minimum number of connections.
ST for several 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 several satellites to several TVs
For this connection option, in addition to convectors with independent outputs, devices such as “diseks” (“daiseki”) are also required. They are designed to receive signals from different satellites via one cable. Dishes are adapted for different protocols. The protocol standard for which a particular drive is intended is indicated on the packaging or on the device itself. For example, “DiSEqC 1.0 – up to 4 convectors.” For the entire 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 optimal connection option, because it is possible to satisfy the interests of all residents of one apartment without significant financial costs.
The most complete kit, which will allow you to connect everything without unnecessary 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);
- attachment 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 installed, you can purchase a client set-top box. 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, with an additional payment, the existing equipment for a new one.
There is no need to install a double converter on the antenna instead of a single head with one output. It will be enough to install an antenna divider near the receiver, where the coaxial cable fits.
Easy connection
A smart card is inserted into the main receiver (CS E501); there is only one in the sales kit. Two coaxial cables coming from the two converter outputs on the antenna are inserted into LNB IN inputs No. 1 and 2 on the same device.
The device plays the role of a server that is capable of decrypting the signal and transmitting it to the GS C-591 client set-top box using a twisted pair cable. After this, all that remains is to connect TVs with set-top boxes using HDMI cables, and you can start searching for channels.
You can configure both devices to adequately display the signal using the appropriate instructions, or use the tips in the video. If everything is done correctly and the operator’s services are paid, then both TVs will show channels independently of each other.
Advantages of this connection option:
- Firstly, there is no need to install a second antenna.
- Secondly, you don’t need to buy a second receiver if you buy a client set-top box, which costs less.
- Thirdly, connecting to one TV costs 1,500 rubles, and to two – 2,000. A system for two TVs costs 1 thousand rubles less.
A television has long been no longer 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 can be placed 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
When trying to figure out how to connect 2 TVs from one antenna, you need to figure out general principle such a procedure, the required tools, and the main steps. 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 there are outputs for connection to the receiver.
After this, you need to take 5 connectors that match the thickness of the outputs on the splitter, as well as adapter plugs. When choosing a cable for an antenna, 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 this option was purchased, but there are only two TVs in the house, it can be closed with a special resistor having 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 complicated, so even an inexperienced user who does not have any radio engineering skills can carry out such manipulations without outside help.
Types of splitters
The main purpose of splitters is to match wave impedances, fix a stable signal, and combat all kinds of noise and interference. A correctly selected splitter guarantees high picture quality and prevents any distortion. But to accept correct solution 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, home TVs use models with two or three outputs, 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 antenna crab is equipped with three outputs, then the resulting TV signal will be 4 dB. Passive models may use transistors or transformers.
As already stated, the number of outputs in splitters can vary from two to eight. If we are talking about 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 one antenna. It is also important to consider the level of attenuation that the splitter has, because the lower it is, the better quality Images.
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 such a device to work, it is necessary to use power. This may 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 when it comes to choosing suitable model there won't be any difficulties. In this case, the principle is appropriate: the more expensive, the better.
At the purchasing stage, it is important to take into account your skills in working with a soldering iron. If they are present, then you can buy a solder splitter, since it is characterized by noticeably less signal loss and the ability to maintain transmission quality.
If you have not had to work with soldering tools, it is better to opt for a regular splitter. However, in this case, you need 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 made your choice, all that remains is to find the suitable connectors. In most cases, a convenient F-interface, which is a wrap-on adapter, is used for this purpose.
Besides, It is important to select a suitable location for the splitter, maintaining the correct distance between it and the TVs. Experts recommend choosing an approximately equal distance, and the cable for the antenna should not be twisted or stretched. You cannot stretch it if there is not enough footage or, conversely, twist it excessively. It is important to first calculate the distance between the splitter and the TV, and also get rid of the excess.
At the cable preparation stage, you need to cut it so that it freely reaches the splitter. Along with the remaining piece of wire, it is necessary to cut off the old plug. After this, you should cut the cable for installation in the F-connector.
First of all, you need 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 4-7 mm. You need to prepare the cable for the plug adapter with a kitchen knife and side cutters.
Features of the procedure
When figuring out how to connect several TVs to one antenna, you need to follow step by step guide. For successful implementation the task requires compliance with the following rules:
It is necessary to connect the cables to the splitter in the correct order, but do not tighten the F-connector too much, 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 furniture or near the baseboard. Experts advise to securely fix the splitter, otherwise it may be damaged if it comes into contact with children or pets. The splitter can be hidden behind any false panel.
If you follow step by step instructions and perform each step correctly, then a clear picture should appear on the TVs without interference or deviations. If something is done wrong, so-called snow will appear on the screen, which indicates a partial loss of signal or a complete absence of image.
Satellite TV and Polish antennas
If any stage of splitter installation is performed incorrectly, a loss of image quality may occur. A similar phenomenon often occurs when working with a satellite dish, when the splitter takes over part of the signal.
To eliminate this 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 splitters with an amplifier support different gain factors, because under some circumstances a strong signal becomes as unnecessary as a weak one. And if you take into account the fact that sometimes it even aggravates the problem, then it is better to abandon this option.
If a classic Polish antenna is installed in the room, then 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 space 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 get rid of poor picture quality on two TVs forever, it is better to buy two antennas at once.
Signal amplification methods
For many TV owners, after connecting several TVs to one antenna, the quality of the displayed picture deteriorates greatly. This is explained by the operating principle of the splitter, which only divides the signal into several streams. To eliminate this negative phenomenon, you need to purchase a special amplifier that works on the crab principle, but has several resistors and an amplification chip.
For such a device, it is necessary to arrange a separate power supply, therefore, when performing installation work You need to think about 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 say 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 worth it 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 noise cutters are present on laptop power supply cords and are designed to combat low quality signal transmission.
There are others no less effective ways amplification of a television signal, but much depends on the antenna itself. So as not to think about how to get rid of the problem Low quality pictures when connecting several TVs to one antenna, it is better to buy them in advance good device 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 units are practically no different 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 long coaxial cable and fixed between the antenna and the splitter.
The amplifier is mounted in front of the splitter and is used to amplify the divided signal, for example, for two or four TVs. Most amplifiers work exactly the same as splitters, so it makes sense to choose just such a device and not buy a splitter.
Connecting two, three or more TVs to one antenna is not a difficult task. Even an inexperienced beginner who does not have professional skills can carry out such manipulation and achieve good results. The main thing is to follow the step-by-step instructions and take into account the recommendations of experienced specialists.
