TNC Jack for LMR-240 Cable, 50 Ohm to 6 GHz
The connector ships as a two-piece kit: the jack body plus a crimp ferrule sized for the LMR-240 jacket diameter. Rated at 50 Ohm impedance with a frequency ceiling of 6 GHz, this is a standard RF interconnect for applications that need a threaded, weather-resistant mate — the TNC interface is the threaded variant of the BNC, offering better vibration resistance and a more consistent impedance match through the coupling nut.
This connector is built for LMR-240 cable specifically — the ferrule ID and crimp die set are matched to that cable's jacket and braid diameters. The shield termination is crimp, not clamp, so the braid is captured uniformly around the ferrule for consistent RF performance through the ground path. The threaded coupling nut (TNC standard) gives a positive mechanical lock that resists vibration loosening — a meaningful difference from a push-on BNC in a mobile or industrial enclosure. The silver housing colour is the natural nickel finish; no paint or coating that could flake into the RF path.
