How to install twist-on coaxial f connectors

Updated April 17, 2017

A twist on F-Connector is an easy way to connect an F-Connector to the end of a coaxial cable. There are special F-Connectors that design to be connected to a cable by twisting on, then another style of an F-Connector crimps on. You need to have the style that twists onto the cable to connect properly.

Take your wire cutters and cut through the outer jacket on the cable two inches down from the end of the cable. Only cut through the outer jacket and do not to cut through the copper wires inside.

Pull off the outer jacket exposing the copper wires. Pull the copper wires down and lay them over the outer jacket that remains. Use the copper wires to twist the F-Connector onto.

Cut off the metal shield that was underneath the copper wires.

Cut through the plastic shield an inch and a half down and pull off the plastic exposing the middle wire. Make sure when you are removing the plastic shield that you don't cut through the middle wire.

Apply silicon grease to the copper wires.

Place the middle wire through the hole in the middle of the F-Connector and slide it over the end of the cable. The bottom sleeve of the connector will slide over the copper wires.

Twist the F-Connect clockwise until the middle of the connector rest on the half inch of exposed plastic shielding. Pull on the connector to make sure it is secured.
