How to connect a TV aerial and cable to a television

Updated February 21, 2017

If your home is wired with a television aerial and a cable television connection, you don't have to choose between the two services. You can connect both the TV aerial and a cable TV connection to your television set. Once the two connections are established, you can view both signals as if the programming was coming from one connection.

Unplug your television or set-top box and turn it around so the back of the set is facing you.

Disconnect the aerial or cable connection from the "UHF," "Antenna In" or similarly worded jack if it is connected.

Examine your splitter and notice one end of the device has a coaxial port while the other end has two coaxial ports.

Plug the coaxial end of the television aerial coax into one of the two coaxial ports on the splitter.

Plug the coaxial cable coming from the cable television connection outlet into the second coaxial port on the splitter. Use the port next to the one you used to plug the television aerial into.

Place one end of a 60 cm (2 feet) piece of coaxial cable into the single output coaxial port on the splitter.

Plug the other end of the coaxial cable into your television or set-top box "UHF," "Antenna In" or similarly worded port.

Plug in the television set or set-top box.

Use your television or set-top box remote control to access the "Menu," "Setup" or similarly worded function.

Select the "Channel Setup" or similarly worded function, then set the input to "Aerial" and perform an "Auto Scan" to locate all available broadcast channels.

Your television or set-top receiver will locate both broadcast and cable television channels.

Scan the channels on your television to make sure all available channels have been found. If you are missing any channels that you know you should have, manually program the channels into your television using the "Channel Setup," "Manual Channel Setup" or similarly worded function.


If the broadcast channels (TV aerial channels) are not clear, adjust your television aerial.
