Replacing a coaxial cable connector can be a very simple task, especially if tackled with a helpful guide and the proper set of tools. Here's what you need to know in order to replace a coaxial cable connector.

Step 1 - Protect Yourself

Make sure that your coaxial cable is disconnected from any device to which it was linked. Trying to replace the connector when the cable is hooked up is certain to present a number of serious safety hazards and result in severe personal injury. When working with cables, safety should always be your top priority.

Step 2 - Remove the Old Connector

If the connector you wish to replace has come loose, as is often the case, you may be able to simply twist it off. If not, you'll need to use a construction knife or wire strippers to detach the worn-out connector.

Step 3 - Prep the Coaxial Cable

You'll now need to make some preliminary incisions. Using your wire strippers, make a small incision toward the end of the cable that requires a connector replacement. This first cut should expose the cable's copper wire. Make another small incision into the cable's protective jacket, taking care not to penetrate the wire braiding located directly beneath the jacket in the process. Gently peel back the cable's protective jacket and wire braiding in order to make room for your new coaxial cable connector.

Step 4 - Begin Attaching the New Connector

Carefully position the replacement connector over the exposed metal pin at the end of the cable. If it isn't a particularly snug fit, you'll need to use a pair of pliers to securely twist the connector into place.

Step 5 - Compress the New Connector

There are two methods to perform the final step in the coaxial cable connector replacement process: compressing and crimping. Both methods are very simple and produce nearly identical results, so it doesn't particularly matter which option you choose. First, we'll explore compressing.

Begin by inserting the end of the cable onto which your new connector was placed into your compression tool, then give the tool's handle a powerful squeeze until the connector has been securely joined with the cable. Apply liquid electrical tape to any exposed areas, allow the substance to dry and you're all finished.

Step 6 - Crimp the New Connector

If crimping is your preferred method of performing the final step, insert the end of the cable onto which your new connector was placed into your crimping tool. Firmly apply pressure to the tool's handle until the new connector has been securely joined with the coaxial cable. After applying liquid electrical tape to any exposed areas and giving the substance ample time to dry, you're done.
