How to Hook Up an Extra TV to the Incoming Cable Service

by Michael Roennevig

Everybody likes to have their own space and get some time to themselves, no matter how close you are to the people you live with. If the atmosphere in your house becomes somewhat fraught and you only have one television that everybody wants to watch though, there's no escape. This predicament can be easily solved by buying some cheap and widely available equipment to split your cable signal. Once you've done so, everyone can watch in separate rooms.


Measure the distance from your cable box to the location you plan put your second television set. Measure the cable that currently runs from your cable box to your first television. Make a note of the measurements once you've done so.


Visit your local audio/visual store and buy coaxial cables with threaded connectors as per the measurements you've taken and a cable signal splitter.


Disconnect the coaxial cable from the back of your first television.


Connect the coaxial cable running from the back of your cable box to the signal "In" port of the splitter.


Connect one end of each of the coaxial cables you purchased to the signal "Out" ports of the splitter.


Connect the shorter cable to the your first television and run the second, longer cable to your additional set.


Turn each television on and select the "RF" option from your sets' input menus to view content from your cable box. The method for doing so will depend on the make and model of your televisions. Consult your sets' user guides if you're unsure how to do this.


  • check You can also buy wireless signal distribution kits. These work by connecting a transmitter to the back of your cable box and transmitters to the RF "In" ports on the back of your televisions.


  • close You'll only be able to view the output of your cable box on each set after you've split your connection. If you want to be able to watch different channels on each television, talk to your cable provider about the installation of a second cable box.
  • close Splitting your cable signal can result in the loss of picture quality. You can buy signal amplifiers form most audio/visual stores to improve your viewing experience if you notice a marked drop in picture quality after splitting your signal.
