How to Hook Up a Splitter to a Cable Box

By Greyson Ferguson

Oftentimes when using cable to watch your television programming, it costs more to put cable in other rooms of your home. However, with a simple splitter you can split the single cable into at least two different cable connections, allowing other televisions to present the programming. But, when using the splitter with a cable box all televisions must watch the same station because the cable box controls what channel is being played.

Things You'll Need

  • Cable box
  • Channel splitter
  • Coaxial cable(s)

Step 1

Remove the coaxial cable running from the "Out" port on the cable box to the "In" port on the television.

Step 2

Connect the single side of the splitter to the "Out" port on the cable box. Most cable splitters look like a "Y," with a single "In" port and two "Out" ports. The out ports are the split signals.

Step 3

Plug a coaxial cable into each free end of the splitter.

Step 4

Connect the other end of the coaxial cable into the "In" port on each television. Power on the televisions and the cable box. You can now watch the cable programming on both TVs.
