It mates with any standard 75 Ohm MCX jack via a snap-on fastening, giving a positive lock without threads. This is the crimp-shield, solder-contact variant: you crimp the braid over the ferrule and solder the centre conductor into the pin. Rated to 6 GHz with 0.15 dB insertion loss — clean through C-band. ## Cable Compatibility — No Guessing This plug is dimensioned for RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179. That covers the common 75 Ohm miniature coax types used in CCTV, SDI video, and baseband data links. Listed as Active — no end-of-life notice or last-time-buy on this order code.","metaTitle":"Amphenol RF 919-137P-71SX MCX Plug, 75 Ohm, 6 GHz, RG-179","metaDescription":"Amphenol RF 919-137P-71SX MCX plug, male pin, 75 Ohm impedance, crimp shield, solder contact.
