BNC plug for RG-58 and similar coax — what it fits and how it terminates
It's built for the cable group that includes RG-58C, 141A, and Belden 9907 — so if you're pulling from a reel of RG-58, this body matches that jacket diameter and dielectric. The contact termination is solder, and the shield is secured with a clamp, not a crimp ferrule. That means you tin the centre conductor, solder it into the brass pin, then clamp the braid under the shell. Frequency range runs to 4 GHz at 50 Ohm, with a voltage rating of 500 V. The body is brass with a silver finish, the centre contact is silver-plated brass, and the dielectric is PTFE — the usual RF-grade build.
Cable prep and assembly — what the clamp shield means on the bench
The shield termination is a clamp. Strip the cable per the manufacturer's specification for RG-58C or 141A, solder the centre pin, then slide the clamp over the braid and tighten the nut.
The base product number is 1478401, and the package is Bulk.
