Coaxial cable splitters

3 ways, with gain and without loss of signal quality

If the antenna is properly installed and tuned, it will receive a quality TV signal. And if this is the case, the user may have a question whether it is possible to connect two TVs to it at once. And if 2 is possible, then what about three or, say, five? Let’s figure out in what cases this is possible and what is required to implement the task.


  • How many TVs can be connected to one antenna
  • Do I need an amplifier
  • Connecting 2 or more TVs to a passive antenna
  • Connecting 2 TVs to an active antenna
    • Through a splitter with matching
    • Through a conventional splitter
    • 9 0414

    • Bonus: we connect 2 TVs without adapters
    • Features of connection to set-top boxes
    • Features of connection to one satellite dish
    • Instead of pins

    How many TVs can be connected to one antenna

    The most familiar option for everyone is “one screen – one antenna”. However, today you will not surprise anyone with the fact that in one apartment there are two, three or more television receivers. Of course, you can install your own antenna for each of them, but it is much more profitable to connect everything to one common, transmitting high-quality signal.

    Technically, double connection is simple: there are special dividers (twins, tees, etc.), with the help of which one signal coming through the antenna cable can be divided into several.

    With sufficient signal strength and the use of high-quality amplifiers, the number of connected TVs to one antenna is not limited.

    Keep the following in mind when splitting the signal:

    1. Power loss possible.
      Under the influence of electromagnetic waves, with which the signal is transmitted, a current occurs in the TV antenna, which flows through the coaxial cable to the receiving device. However, this current is weak. Any additional resistance leads to losses and eventually damping. Therefore, when connecting a second TV, it must be borne in mind that the entire system will work either in an area with a strong TV signal, or it is necessary to foresee the connection of an amplifier in advance.
    2. Dividers (aka splitters) come in different designs.
      It is important to remember here: a satellite splitter for receiving terrestrial digital television is suitable, on the contrary – no. In addition, there are dividers with and without agreement. Most of the available models sold in stores use conventional capacitive or transformer isolation, which means that you need to provide a place to power the amplifier even before the divider.
    3. You need to connect two TVs to the same antenna, but different set-top boxes.
      Connecting to a single receiver is technically simpler, but it combines the signal so that the same picture will be synchronously broadcast on both screens.

    Connecting to each TV with its own individual antenna is:

    Cool! Waste of money!

    Do I need an amplifier

    Amplifier with power control

    . Therefore, in most cases it is necessary.

    It will definitely be required in situations where:

    • the signal is of good quality but low power;
    • two or more splitters installed;
    • long connecting cables are used.

    In addition, the amplifier is more likely to be superfluous when using cable and satellite TV. For them, the main thing is not to degrade the incoming signal, and the amplifier inevitably introduces distortion.

    Finally, if the signal is critically weak, the amplifier is useless. He will not be able to raise the TV signal received by the antenna to the desired level: there is simply nothing to amplify.

    To understand if an amplifier is needed, you need to measure the signal level with a multimeter or at least a tuner scale. If the level is high enough, you can do without additional improvements.

    Connecting 2 or more TVs to a passive antenna

    Passive ones are those that do not have a built-in amplifier. They receive a signal only due to their shape. If amplification is required, then it is provided by an additionally connected external unit.

    The easiest way to connect two TVs is to install a splitter with the appropriate number of outputs on the antenna cable.

    The best options here are:

    for 2 TVs – SAH 204F;

    for 3 – SAH 306F, etc.

    for 4 – SAH 408F, etc. . If a larger number is required, it is already necessary to build a chain of dividers, splitters and at least one amplifier.

    Another option for connecting three or more TV receivers is to use an active splitter. In this case, the cable from the antenna is connected to a divider that has an amplification stage, and it, in turn, transmits a signal to another passive type splitter.

    The active splitter can have a separate power input or use current supplied from the receiver through the same cable carrying the antenna signal.

    We connect 2 TVs to an active antenna

    An active antenna is a device in which the amplification unit is its structural part. At the same time, it most often receives power via a coaxial cable. You can connect as many TVs as you need to such an antenna in two different ways.

    Through a divider with matching

    The amplifying unit needs power. However, if you use a conventional divider, the current will not go to the antenna: there is a transformer or capacitive isolation. To supply current to the amplifier, you will need a special device – a divider with a power pass (Power Pass).

    To connect 3, 4 or more TVs to this splitter, you can use externally powered active splitters. The connection chain is built in this case in the same way as described above for a passive antenna.

    Through a common splitter

    If there is no power feed through splitter, current can be applied in the section between it and the splitter. In this case, a tie-in fastener and a power supply separator are used.

    We get the following:

    • the required current is supplied to the amplifier;
    • the signal goes through the divider to the receivers.

    If you need to connect 3 or more TVs, you need to take a splitter with the appropriate number of connectors. The basic scheme is the same.

    In the event that you need to connect 2 TVs, and the splitter has three output connectors, the free one must be drowned out with a 75 Ohm ballast resistor (such is the resistance of the antenna cable).

    Bonus: we connect 2 TVs without adapters

    According to amateur TV technicians, in some cases adapters in the form of dividers are not only unnecessary, but even harmful.

    Experts suggest the following scheme:

    1. An antenna and two coaxial cables are taken.
    2. The ends are trimmed. The distance at which the top insulation must be removed is determined experimentally.
    3. The braid and foil are untwisted for the cables and a general twist is made from it. The central wires remain separate.
    4. These two wires are screwed into place in the antenna. A twist of shielding material is attached in the same place where the shield should normally be on a single cable. The main thing at the same time is to make sure that the wires do not come into contact with the screen.

    Expert opinion

    Vitaly Sadovnikov

    Specialist in connecting and setting up digital television

    Ask a question cable and splitter.

    However, technologically it is more difficult, in addition, it changes the characteristics of the circuit in an unpredictable way, so you can use this connection option, but the result is not guaranteed.

    Features of connection to set-top boxes

    In the event that receivers or tuners are used, there are two ways to connect a second TV. Which one is suitable depends on the design of the receiving equipment.

    In the event that at least one of the receivers has an RF-OUT connector, the connection is made as follows:

    1. The first receiver is connected to the antenna through a regular cable and the appropriate socket on the body.
    2. The second receiver is already connected to the first one. To do this, its design should provide for the possibility not only to connect to the antenna, but also to relay the signal. Typically, these set-top boxes will label the output jack “RF Out” or similar.

    Important! When using two receivers, in order to watch not only free, but also encrypted channel packages, you will have to purchase two smart cards and pay a subscription fee for both sets of equipment.

    If none of the receivers has an output socket, you will need to purchase a divider. Installation using a splitter in the general case looks like this:

    • antenna cable from the dish is connected to the splitter;
    • connect each receiver with the same shielded cable to the corresponding splitter output jack;
    • Each receiver is independently tuned to receive.

    Features of connection to one satellite dish

    If the antenna converter has two outputs (for signals with horizontal and vertical polarization), you can connect a separate receiver to each of them. Or use a multiswitch divider: both outputs of the converter are connected to it, and it distributes signals to 2-3 receivers. However, here it must be borne in mind that you will need to pay separately for channels for each device.

    Finally, two conversion units can be connected to one cymbal. Then you can connect your receiver to each of them. However, you need to remember: you cannot use two converters to receive channels from one satellite. Fortunately, the geostationary orbit is filled quite densely and an additional satellite will almost always be in the reception area.

    When using an RF modulator, the procedure is as follows:

    1. The receiver is connected and configured to receive satellite channels.
    2. An RF modulator is connected to its audio and video outputs, which carry a low-frequency signal (AV, SCART, etc.). This device converts a low frequency signal into a high frequency signal and divides it into multiple RF outputs. It is already possible to connect ordinary 75 ohm coaxial cables to them.
