Repairing your TV aerial or antenna is pretty straight forward and does not require any specialized electrical skills.An indoor TV antenna attaches to a television set through a coaxial cable attached to the antenna’s signal output and the TV’s signal input. A broken coax connector at the end of a coaxial cable that is permanently attached to an antenna must be replaced or it cannot be used. To fix the antenna’s coax connector, a replacement coax connector from a hardware store and a few tools commonly found around the house are needed.
Cut off the coax connector from the end of the antenna's cable with wire cutters. Place the base on the cable and push it back 3-4 inches toward the other end of the cable. Repeat this with the collar, only push it 3 inches in total.
Grip the sides of the collar with the jaws of the needle-nosed pliers. Squeeze the needle-nosed pliers to secure the collar to the cable.
Make a 2-inch slit from the cut end with the blade of a utility knife. Peel back the outer insulation from the cable with your fingers. Cut the outer insulation off from the cable with the scissors.
Pull the copper wire surrounding the plastic sheath at the center of the cable back. Twist the copper wire between your fingers to form a ridge around the plastic sheath.
Cut an inch in from the end of the plastic sheath with the blade of the utility knife. Peel back the plastic sheath from the copper wire. Cut the plastic sheath off the cable with the scissors.
Thread the plastic collar cover plate through the copper wire and up against the collar. Place the connector shell over the plastic collar cover plate and push it onto the cable until it covers the collar. Push the base up against the connector shell. Screw the base into the connector shell.
