How to connect a coax cable to a TV wirelessly

Updated June 15, 2017

With the cost of satellite and cable television subscriptions continuing to rise, many consumers want alternative methods for watching multiple TVs. Wireless video sender devices save the hassle of running coaxial cables through your home or buying additional satellite and cable set-top boxes. Most of these wireless devices transmit through doors, walls, floors or windows with no interference with a range of up to 150 metres (500 feet).

  1. Screw the connector end of one piece of coaxial cable into the wall outlet and the other end into a cable splitter.

  2. Connect the other two pieces of cable to the cable splitter, screwing one to the TV and the other to the RF input on the video sender's transmitter unit.

  3. Use one set of RCA cables to connect the transmitter to the first television, then use the other set to connect from the "AV out" connector on the receiver to the second TV. The AV out will be labelled and may also say "out" or "output." It provides a video signal acceptable for a television AV input.

  4. Open the on-screen menu with the remote control and select a name for the new wireless network. This will identify all devices either sending or receiving the wireless signal.

  5. Select a channel for the cable transmission to display on. Most often, this will be a number between "1" and "11," though instructions received with your video sender may assign a different wireless channel.

  6. Tip

    If you experience interference when sending a wireless signal, try removing other wireless devices from the area that could potentially disrupt the signal.

    The cable transmitter and receiver should be at least 9 metres (30 feet) apart to avoid interference.

    Some wireless video sender devices allow the user to set a password for all the devices in the network, encrypting the signal.


    Some wireless devices may not be compatible with your TV model.

    If your wireless device does not have a built-in TV tuner, you will not be able to watch separate channels on the TVs being connected.
