The cable group covers RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 — the common 50 Ohm flexible and low-loss cables used in automotive telematics, GPS antennas, and short-run RF interconnects. ## Cable Selection and Crimp Assembly Pick the cable from the supported list — RG-58 for general-purpose runs, LMR-195 for lower loss over longer distances, or Belden 9907 for plenum-rated installations. The 100 mating cycle rating means this is a set-and-forget connector for field-installed cable assemblies, not a daily test-port connector. Crimp the centre contact with the correct hex die for the pin diameter, then crimp the ferrule over the braid. ## RF Performance and Link Budget The 0.3 dB insertion loss is a single-connector figure — budget it once per mated pair in the link calculation. At 4 GHz the VSWR is not stated in the spec, but the 50 Ohm impedance and the PTFE dielectric suggest a return loss better than -15 dB across most of the band when terminated to the correct cable. The gold-plated centre contact keeps the contact resistance low over the 100-cycle life, which matters for passive intermodulation in transmit paths.","metaTitle":"FA1-NBSP-C04-1 SMB/Fakra Plug, 50 Ohm, 4 GHz, RG-58/LMR-195","metaDescription":"FA1-NBSP-C04-1 SMB/Fakra plug, male pin, panel mount with flange. 50 Ohm, 4 GHz max, 0.3 dB insertion loss.
