How to Connect a Coax Cable to a TV Wirelessly

By Stephanie Sigafoos

With the cost of cable television continuing to rise, many consumers are seeking alternative methods to watch multiple TVs using just one cable line. Wireless solutions now exist, saving the user from having to run coaxial cable through a home and also from having to purchase additional cable boxes through a cable company. Most of these wireless solutions will transmit through doors, walls, floors or windows with no interference and transmission that may range from 300 to 500 feet.

Things You'll Need

  • Three coaxial cables
  • Coax cable splitter
  • Two televisions
  • RCA/composite cables
  • Wireless RF transmitter/receiver and remote

Step 1

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

Step 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 transmitter.

Step 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 (audio/visual) out will be labeled and may also say "out" or "output." It provides an analog video signal acceptable for a television AV input.

Step 4

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

Step 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 transmitter/receiver may assign a channel such as 2 or 3.

Tips & Warnings

  • 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 20 to 30 feet apart to avoid interference.
  • Some wireless cable TV 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.
