How to Install Coaxial Cable in Walls

Coaxial cable is one of the standard connections for sending a television programming signal to a TV. Capable of carrying a signal hundreds of feet, coaxial cable connects quickly with threaded couplers on either end. The cable can be installed virtually anywhere, but may not look very attractive running along the baseboard of a living room or home theatre. For a more professional looking installation, coaxial cable can be installed in walls with a tool called a fish tape. That way, the cable won't create a tripping hazard or clash with the decor.

  1. 1

    Cut off the electricity to the room where the coaxial cable will be installed in the wall. This prevents an electrical hazard while working with metal tools inside the wall.

  2. 2

    Determine the two points in the wall where the coaxial cable will enter and exit. The two points should be either horizontal or vertical to the floor, rather than diagonal, which is a more difficult path to run cable with a fish tape.

  3. 3

    Drill a 1/2-inch hole at the two positions where the cable will be installed.

  4. 4

    Insert the fish tape into one of the holes and guide the hook on the end toward the second hole.

  5. 5

    Push the end of the fish tape out of the second hole far enough to attach the end of a coaxial cable, which can be looped through the hook with an overhand knot. Push the end of the fish tape with the attached cable gently back into the hole.

  6. 6

    Pull the fish tape back from the first hole, dragging the coaxial cable along with the metal fish tape.

  7. 7

    Remove the fish tape and cable from the wall, pulling the coaxial cable out far enough that it cannot accidentally fall back inside the wall.

  8. 8

    Place a faceplate over the end of the cable and attach the plate to the wall with two screws.

Tips and warnings

  • Measure the distance for running the coaxial to be sure the cable is long enough to cover both holes. Discovering that the length of cable is too short for the job means pulling out the fish tape from the wall and starting over again.
  • Do not turn on the electricity to the room until the cable is installed and the fish tape removed from the wall.
