How to Transfer Cable to a Second TV Wirelessly

by David Lipscomb

Wireless radio frequency is a ubiquitous technology found in remote controls, whole-house automation devices, and audio/video transmission and distribution. Sending wireless cable TV signals from the main room to a second area fits under this umbrella. Wireless RF works by creating a dedicated channel of transmission from the sending device to the receiving device. In so doing, it rejects quite a bit of interference from competing devices and household appliances, such as microwaves.

Access the back of the cable decoder box. Locate the RF coaxial output. Find the corresponding input on the rear of the RF sending unit.

Screw the coaxial cable onto the RF fitting, using a clockwise motion. Route the cable to the RF input on the sender and screw the cable onto that RF fitting in the same manner.

Open the paddle of the sender and aim it in the approximate direction of the room to which the signal will be sent. Plug the AC adapter on the sender into the wall.

Plug the composite A/V cables from the back of the RF receiving unit into the back of the TV to which the signal is being transmitted. Push on the cables, following the color coding.

Plug the AC adapter from the receiving base into an adjacent output. Flip up the paddle, aiming it in the approximate direction of the sender's paddle.

Flip the sender's channel to "Channel 1." Do the same for the receiving unit. Change the channels if one offers less interference than another.

Plug the 3.5mm jack on the infrared flasher (included with the RF kit) into the indicated jack on the sending box. Remove the adhesive backing on the rear of the flasher. Stick it directly onto the infrared sensor on the cable box, to the immediate left or right of the front panel display. This allows channel changing and cable-box operation from the second room.


  • check Plaster and lath walls can create interference that is greater than standard wood stud/drywall structures, due to the amount of metal. Place the sender and receiver closer together if this proves true in your installation.
