The 50 Ohm impedance and DC to 6 GHz frequency range put it squarely in the GPS, satellite radio, and cellular signal path — not a general-purpose RF connector, but a tuned 50 Ohm link for cable groups like RG-58, RG-141, RG-303, LMR-195, and Belden B7806A. ## Cable Prep and Termination This jack comes as a 3-piece kit: the connector body, the centre contact, and the ferrule. The centre contact crimps onto the signal wire (phosphor bronze, gold-plated), and the shield termination is a crimp-over-braid style using the supplied ferrule. The cable groups it supports are all 50 Ohm coax with a nominal 0.195-inch jacket diameter — RG-58, 58A/B/C, 141, 303, LMR-195, and Belden 7806A/9907. The dielectric material is PTFE, so the centre conductor stays centred through the crimp cycle and the impedance holds through the transition. ## RF Performance and Mechanical Life Rated insertion loss is 0.3 dB across the band, and the maximum operating frequency is 6 GHz — enough for 5 GHz Wi-Fi or dual-band GNSS without a notch. The 100 mating cycles are typical for a Fakra latch-lock connector; the gold-plated centre contact and nickel-plated zinc die-cast body handle the wear.","metaTitle":"2FA1-NDSJ-C04-0 Amphenol RF SMB Fakra Jack, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 2FA1-NDSJ-C04-0 SMB Fakra jack, female socket, 50 Ohm, DC to 6 GHz, 0.3 dB insertion loss.
