UHF Mini Jack for RG-58 Coax — Field-Install Kit
It ships as a three-piece kit: the connector body, one crimp contact, and one crimp ferrule — everything needed to terminate a cable in one order line. Rated for RG-58, 58A, 58B, and 58C cable groups, this jack handles signals up to 2 GHz with a voltage rating of 335 V. The 500-cycle mating life suits applications where the connector is disconnected and reconnected regularly — test equipment, portable radios, or antenna patch panels. The impedance is non-constant, which means this is not a precision 50-Ohm constant-impedance interface; it is a UHF-series design intended for lower-frequency RF and general-purpose coaxial interconnects where a controlled impedance line is not required.
The ferrule crimps over the braid; the contact crimps onto the centre conductor. The silver-coloured housing accepts the RG-58 cable group diameters — no adapter or step ferrule needed. The threaded coupling provides vibration-resistant mating — the nut must be hand-tightened plus a quarter turn with a wrench for full engagement.
