How do I Install a Twist on a Coaxial Cable Connector?

Coaxial cables can be terminated in a variety of ways. One such option is through use of a twist-on F connector. These connectors are useful if you do not possess a coaxial crimp tool, and facilitate easier swapping of the connectors in the event of damage. Although not as water-resistant as a crimp-on version, twist-on coaxial fittings are durable enough for conventional indoor use.

Step 1

Cut the coaxial cable to the desired length, using the wire cutters. Try to make the end of the cut as straight as possible.

Step 2

Lay the end of the coaxial cable into the cable stripper, butting the end of the cable against the stopper.

Step 3

Grip the handles of the tool. Rotate the stripper three or four times in both directions. Pull off the unwanted outer insulation by hand, exposing the copper braided shield within.

Step 4

Separate the braid by hand. Fold the braid back against the outer jacket. Do not be concerned if a few of the shield strands fall off; this is normal.

Step 5

Apply a liberal amount of silicone lubricant to the shield braid. This waterproofs the connection and aids in twisting the connector on.

Step 6

Push the connector as far as it will go. Clamp the pliers or vice grips around the knurled collar of the connector. Twist the connector clockwise, firmly gripping the tool. Continue until the inner flange of the connector sits firmly against the end of the white plastic tube surrounding the copper center conductor.

Step 7

Snip off any excess braided copper shield protruding from the base of the connector, using the tip of the wire cutters. Cut off excess center conductor sticking out from the end of the connector with the cutters.
