How to Hook Up a Cable AB Switch

Save

An A/B switch is an accessory that is used to connect two input signals, such as cable and satellite (or an antenna), to a television. This allows you to switch between each of the input sources, depending on the program you want to view. If you have a separate cable and antenna connection for a high-definition TV, an A/B switch may be needed. This is because an HDTV has only one coaxial input.

Things You'll Need

  • A/B switch
  • Connect the end of the coaxial cable coming from the antenna to an "In" port on the A/B switch.

  • Connect the end of the coaxial cable coming from the cable to the other "In" port on the A/B switch.

  • Connect one end of a coaxial cable to the "Out" port on the A/B switch.

  • Connect the other end of the coaxial cable to the "In" port on the back of your TV.

  • Set the A/B switch to the "Ant" setting.

  • Turn on your television. Change the channel to 3 or 4. The programming will appear on one of the two channels.

  • Set the A/B switch to the "Cable" setting to view the cable programming. Set it back to "Ant" to view programming off the antenna.
