Coaxial Cable Installation

To connect a coaxial cable to a traditional RCA or BNC connector, the installer should follow this process:

  • If using a stripping tool, the roundness of the cable should be determined.  (To properly function, most stripping tools require a round cable).
  • To restore the cable’s roundness, gently squeeze the cable between thumb and finger.
  • Using a stripping tool, strip the cable to a dimension of .250” exposed braid and .157”exposed center conductor.  The center conductor can be .125 inches - .157 inches in length.
  • Then separate the braid from the dielectric – folding the braid back against the cable jacket.  Make sure that no braid strands are wrapped around the center conductor.  Trim any strands that are loose or  in the way.
  • Slide the connector’s compression support ring over the cable and the folded braid.  Seat against the jacket cut point.
  • Straighten the center conductor, if necessary, and slide the pin over the center conductor, spin the pin assembly until the pin is fully threaded against the cable’s dielectric.  Pull the pin holder straight out to remove it from the pin.  Make sure that the pin is straight in line and not crooked or tilted.
  • Inspect the assembly to ensure that no braid shield strands are in the exposed dielectric area between the compression support ring and the pin base.  Loose strands will cause the shield to short to the center conductor.
  • The connector assembly should then be placed into the rear of the BNC or RCA plug and inserted until the ring is visible in the sight window and it “clicks.”  The click is the center pin being secured by a mechanism within the connector body.
  • While maintaining pressure on the cable to ensure that the assembly stays properly seated within the connector body, apply the crimping tool and crimp. 
  • Remove the tool and inspect the crimp to make sure that the connection is fully viable.
