This plug is designed for cable group RG-178, 178A, 178B, 196, 196A, and M17/93-RG178 — all 50 Ohm, small-diameter coax with a solid or stranded center conductor. The center contact is soldered, and the shield is terminated with a crimp ferrule. The snap-on fastening means no coupling nut to turn — push it onto the jack until it clicks, and you're mated. The PTFE dielectric keeps signal loss low and impedance stable across the full temperature band.","metaTitle":"Amphenol RF 919-388P-51S MCX Plug, Male Pin, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 919-388P-51S MCX plug kit for RG-178/196 cable. 50 Ohm impedance, 6 GHz max, 500 mating cycles.
