How to Amplify the Cable Signal

By Techwalla Contributor

If you need to hook a new TV up to your cable line and you want to ensure that you aren't weakening the signal to your other televisions on the line, you can use a splitter/amplifier to keep the cable quality. You can install the splitter/amplifier in a few steps.

Things You'll Need

  • Splitter/Amplifier
  • Cable extension, 3-foot length

Step 1

Purchase a splitter/amplifier from an electronics store. This device should have a few female cable jacks and a power source that you will plug into the wall.

Step 2

Pick up an extra cable extension cord with two male plugs to connect your television to the line.

Step 3

Plug the cable from the wall jack into the splitter/amplifier input jack.

Step 4

Plug the outgoing cable into the output jack on the splitter/amplifier and into the TV.

Step 5

Connect any other cables to the splitter/amplifier that are going to other television sets from the original cable feed from the wall jack.

Step 6

Plug in the splitter/amplifier. Your cable signal is amplified.

Tips & Warnings

  • If you use a cable modem, get a bi-directional amplifier to allow the signal to travel in and out, which is necessary for a modem to send and receive data.
