How to Crimp RG6 BNC

Electronic devices use a dizzying assortment of cables and connectors to communicate with each other. One of the common ones is the BNC connector, widely used to make 75-ohm connections between pieces of equipment. The BNC is a push and twist type of connection, with one connector having a pair of lugs and the other having a ring that locks over it to make the connection. They're typically used on smaller RG-59 or larger RG-6 wire. Connections are easily crimped onto either cable in the field, for repair purposes or to make custom cabling.

Things You'll Need

RG-6 cable
Four-part BNC crimp-on connectors
Coax cable stripping tool
Coax cable crimping tool

Instructions

- 1
  Trim the end of your RG-6 cable if it is damaged, or if you're replacing a broken end. Separate the four pieces of your BNC connector and drop the crimp ring over the end of the cable.
- 2
  Strip approximately 1/2 inch of the outer insulation from your cable, revealing the braided shielding. Pull back the shielding like a banana peel, so it covers the outer insulation and bares the center connector and its white plastic dielectric covering.
- 3
  Slide the plastic sleeve of your BNC connector over the dielectric to stiffen it. Cut away any exposed portion of the dielectric, leaving approximately 1/8 to 5/32 inch of the center conductor bare.
- 4
  Position the center pin of the BNC connector over the bare wire and slide it in as far as it will go. The flared end of the pin should meet up with the dielectric. If it doesn't, remove the pin and shorten the center wire slightly. Slide the pin back on and crimp it in place.
- 5
  Push the body of the connector into place over the end of the cable. You'll feel the center pin click into place when it's pushed all the way on. Slide the braided wire back so that it covers the body of the BNC connector. Slide the crimp ring forward so that it covers the layer of braid.
- 6
  Crimp the ring in place using the RG-6 portion of your crimping tool. If you are repairing a damaged cable, you're now finished. If you are making up a custom cable, repeat this process at the other end.
