Learning how to work with coaxial, or coax, cable wire is a handy skill to learn because it allows you to install cable in your house without having to pay the cable company to come out and do it for you. Working with it is much different from working with standard wire found in most electronic devices. These wires are much safer to work with because they are connected more like plumbing than electrical wires.

  1. 1

    Cut the coax cable wire in half. Place either end of the severed wire inside the coax cable stripper, close the clamp connection and spin the coax cable stripper around the cable. The cable stripper makes two cuts in the cable. The first cut allows you to strip the entire casing from the copper wire, while the second cut strips the outside layer and leaves the foil casing in place. Repeat this step for the other side of the cable.

  2. 2

    Remove the cable from the stripper. Twist the insulation off of the copper coax connection of the first cut area of the cable. Twist the outside casing off of the second cut area of the cable to expose the foil-coloured insulation. Repeat this step for the other side of the cable.

  3. 3

    Place a coax cable connector head onto the top of the cable and push it on so that the foil insulation fits through the centre hole of the connector head. Place the crimping tool over the base of the connector that rests over the coax cable, then crimp down the coax cable tightly. A crimper is a four-way crimping tool that evenly crimps all four sides of the cable connector. Repeat this step for the other side of the cable.

  4. 4

    Screw each side of the cable into the two-way connector to join the cables.
