The following steps will guide you through the preparation and termination process for coaxial cable with compression connectors. Following these guidelines will help you receive the optimum performance from the coaxial cable. 

Compression tool, cable stripper and compression connectors for terminating coax cable.

Step 1: The tools you will need:

Insert the coax cable into the cable stripper.

Step 2: Adjust the blades of the stripper to expose ¼ inch of the conductor and ¼ inch of the insulation. Insert the coax cable into the strip cartridge to the adjusted length.

Removing the jacket to expose the center conductor.

Step 3: Holding the cable near the tool, rotate the cutter around the cable (three to five full turns) to score the jacket and cut through the insulation. Be sure the braid is cut (you can hear when the wires of the braid have all been cut). Then flex the jacket to separate and slide it off to expose the center conductor.

An intact center conductor reduces the chance of shorts.

Step 4: Flare and bend back the remaining outer braid onto the cable outer jacket. Make sure to remove any stray or loose braids. Stray or loose braids can cause shorts if they touch the center conductor. Verify that the center conductor and the insulation are not nicked or scored.

  • When handling cables with multiple braids, such as quad-shield, refer to the manufacturer’s literature for proper braid handling techniques.
1/8 inch of the center conductor protrudes from the connector.

Step 5: Insert the sleeve ferrule and BNC body onto the coaxial cable. Firmly push the cable as far as possible or until 1⁄8 inch of the center conductor is protruding from the connector. 

  • Make sure the connector is fully seated and the white dielectric material is firmly pushed against the inner stop of the connector. You can see this by looking into the open end of some connectors.
Connector is firmly attached to the cable.

Step 7: Inspect the connection making sure that there’s no braiding exposed and that the connector is firmly attached to the cable.

Coax cable and connector inserted into the crimping device.

Step 6: Insert the cable and connector into the crimping device, making sure that it is positioned firmly. Squeeze the crimper handle tightly. Use a ratcheting tool that does not release until the proper crimping displacement has been applied for the specific cabling and connector type. Once the tool releases after the final “click,” the crimp should be complete.
