Product details

BNC Plug for RG-59 Coax — 50 Ohm, 4 GHz, Full Kit

The 31-212-RFX: The kit includes six pieces: the connector body, a braid clamp, a cable clamp, the centre contact, a gasket, and a washer.

Termination and Cable Prep — Solder Centre, Clamp Braid

The included gasket seals the cable entry, and the washer prevents galling between the nut and the body. For RG-59, strip the jacket per the manufacturer's recommended dimensions — the clamp accommodates the braid diameter typical of that cable group.
