The latch lock fastening gives a positive click when fully mated — you feel it seat. ## Cable Prep and Crimp — What It Takes The compatible cable groups are RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 — that covers the common 50 Ohm small-diameter coax you see in GPS antennas, cellular modems, and short RF jumpers. You'll need the correct crimp die for the cable OD and the center contact size — don't guess the hex size.","metaTitle":"Amphenol 3FA1-NCSJ-C04W0 SMB Fakra Jack, 50 Ohm, 3 GHz","metaDescription":"3FA1-NCSJ-C04W0 Amphenol RF SMB Fakra jack, female socket, 50 Ohm, 3 GHz max.
