Coax cable is popular for many audio and other noise-sensitive systems. It provides a rugged connection while being flexible and difficult to short out. BNC connections are the most common type of connector used with coax cable. Preparing the coax properly for a BNC connector is important for ensuring safe operation of your equipment.
Instructions
1. Inspect the coaxial cable to ensure it is not damaged. If there is any question, use a DMM (digital multimeter) to check the resistance between the center conductor and the shield layer is at least 50K ohms. Using the utility knife, carefully cut the outer insulation layer of the coax 1/2 inch back from the end of the cable. Peel the insulation away and inspect the shielding (wire mesh) underneath for damage.
2. Using the diagonal cutters, trim 3/8 inch of the shielding back from the end. Press the remaining mesh back along the axis of the cable to loosen it for later installation of the BNC connector.
3. Using the utility knife, carefully cut the inner insulation (usually a white plastic) 1/4 inch back from the end of the cable, exposing the solid center connector. Inspect the line of the cut to ensure the center conductor was not damaged. The coaxial cable is now prepared for installation of the BNC connector.
