How to Wire a Coaxial Cable Wall Box

by Joe Murray

    A wall mounted cable TV outlet allows you to access a cable signal by fastening a coax cable with an “F” connector to the output. The wall plate also appears far more aesthetically pleasing than a hole in the wall with a cable wire sticking out. Most cable TV installers leave you with the latter, but there is a relatively quick and easy solution. With a fast trip to your local electronics retailer and a few household tools you can install and wire a coaxial cable wall box that looks just like a professional setup.

    Step 1

    Select the general area where you wish to locate the coaxial wall plate. Use a stud finder to be certain no studs lie under the sheet rock at this location. Mark the specific point where you want to cut through the wall and sheet rock with the point of your Phillips screwdriver.

    Step 2

    Cut a 1- to 2-inch round hole into the sheet rock with the hole-cutting bit on an electric drill and remove the resulting plug of sheet rock. If the coaxial faceplate kit came with a template, trace its outline over the round hole in the sheet rock and cut away the remaining sheet rock with the small saw. You can use a drill bit to make starting holes for the saw in the four corners of the template. If there is no template included, place the faceplate over the hole and mark the two screw holes with a pencil. Remove the faceplate and make a hole large enough to reach the coaxial cable without cutting near the two marks you made for the mounting screws.

    Step 3

    Pull 75-ohm coaxial cable from inside the wall through the rectangular hole in the sheet rock. If the end of the coaxial cable does not have a female “F” connector mounted on the end of the wire, attach it and use a crimping tool to secure the connector tip to the cable.

    Step 4

    Screw the female “F” connector to the male tip on the back side of the coaxial faceplate. Tighten with pliers.

    Step 5

    Secure the two mounting brackets that came with the coaxial faceplate kit to the upper and lower areas of the rectangular hole. Make sure to measure the distance and mark the exact location for the brackets before attaching them.

    Step 6

    Fasten the faceplate to the mounting brackets using the two mounting screws that came with the faceplate kit.

    Tips

    • Pulling wires through walls can be facilitated by using a length of string attached with duct tape to the end of a straightened wire coat hanger. Poke the end of the coat hanger through the outside and into the interior of the wall. Grab the coat hanger, pull till you can reach the string, then pull the string to the end of the coax.
    • When pulling wire on multiple levels always start with the top floor.
    • For the best transmission results use gold-plated connections.
    • Heed the wisdom of the old saying and measure twice, cut once.

    Warnings

    • Using long lengths of cheap or thinly shielded (RG-59) coaxial cable can result in line loss and inferior signal. If you are running over 15 yards of cable, use heavy-duty coax: RG-11 outside and RG-7 or 9 inside.
