How to Extend Coaxial Cable

By Art Corvelay

A coaxial cable is a cable that can transmit large amounts of audio and video data. These cables are typically used to transfer television data to your cable box or TV. Coaxial cables are especially sturdy because they are completely insulated in a fire-safe teflon coating. If you are trying to run a coaxial cable from a wall outlet that is a far distance to the end source, you may have to extend your cable. It is not difficult to extend a coaxial cable as long as you have the right tools.

Things You'll Need

  • 2 coaxial cables
  • Coaxial cable extender

Step 1

Plug the first coaxial cable into the wall outlet. Turn the metal piece on the end of the cable to the right to tighten it.

Step 2

Plug and tighten the opposite end of the first coaxial cable into one end of the coaxial cable extender.

Step 3

Take the second coaxial cable and plug and tighten one end into the opposite end of the cable extender.

Step 4

Plug the opposite end of the second coaxial cable into the source.

Step 5

Repeat the process with multiple coaxial cables and cable extenders if you need to extend the cable even more.

Tips & Warnings

  • Running a coaxial cable through an extender can decrease the signal from the wall outlet. It is usually not enough to inhibit TV viewing, however.
