It ships as a complete field-termination kit: one connector body, one center contact, one ferrule, and one piece of heat shrink. Snap-on fastening gives a quick, positive lock; the gold-plated brass body and gold-over-brass center contact handle 500 mating cycles without signal degradation. This connector is designed for RG-179 double braid cable — the cable group is called out explicitly, so there's no guesswork about dielectric diameter or braid coverage. The included heat shrink covers the solder joint and ferrule for strain relief and insulation. The PTFE dielectric in the connector body matches the cable's dielectric for a consistent 75 Ohm impedance through the interface.","metaTitle":"Amphenol 142190-75 SMB Mini Jack, 75 Ohm, RG-179 Kit","metaDescription":"Amphenol 142190-75 SMB mini jack, 75 Ohm, for RG-179 double braid cable.
