Appendix A: Coaxial Cable
The number one problem encountered during installation is wiring
technique and connectors. Ensure that no stray braid wires are
touching the center contact pin when pushing it into the connector.
This may cause the equipment to function intermittently or with
reduced range. Good wiring techniques will eliminate considerable
troubleshooting time later in the installation.
Required Materials
• RG-58/U coaxial cable with 50-ohm impedance (nominal), solid copper
center conductor, 55% tinned copper braid or better, 100% foil shield
coverage (for example, Belden 9310).
• 3-blade rotary coaxial cable stripper
• 3-piece crimp type male BNC connector (for example, Amphenol 31-
320). Screw-on connectors are NOT recommended. They short to
ground easily and can be pulled apart.
• Diagonal cutters
• BNC crimpers
• Multimeter with continuity check
Attaching the BNC Connector
1. Cut RG-58/U coaxial cable and trim jacket .
2. Slip the crimp sleeve over the cable. Place the contact pin onto
the inner conductor. The end of contact and insulator must be
butting and square .
3. Ensure that the pin goes to center, braid to shield.
4. Crimp with appropriate tooling .
5. Flare the outer braid and gently but firmly push the contact into
the connector housing until a gentle snap is felt, indicating the
contact is in place .
6. Slip the crimp sleeve in place, butting the flange against the
connector body .
7. Crimp with the appropriate tool .
8. Test for continuity of the inner conductor from connector to
connector. Test for continuity between connectors. Test for
insulation between inner conductor and connectors .
