Things you need

  • 18 inches of 14-gauge copper wire

  1. 1

    Carefully bend your copper wire into a loop, with the ends of the wire free.

  2. 2

    Make a small loop at each end of the wire using your needle-nosed pliers. Size the loops so the bolts slide through with a minimum of clearance.

  3. 3

    Place a washer onto a bolt, then slide the bolt through one of the small loops at the end of the wire. Slide another washer onto the bolt and then tighten the nut onto the bolt with your fingers. Repeat the process with the remaining bolt and the other loop of wire.

  4. 4

    Slide the connectors of your transformer underneath the nuts---one tab per nut, and then tighten the nuts to hold the transformer in place.

  5. 5

    Connect your RG-6 cable between the antenna's transformer and the television's antenna input.
