It carries the Code A mechanical keying with a black/jet housing color, which prevents cross-mating with other FAKRA code variants in multi-connector harnesses — a common failure point when a GPS antenna lead gets swapped into a satellite radio port. The crimp shield termination and solder center contact are standard for RG-58-class cables — the listed cable group covers RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. The right-angle free-hanging orientation suits tight routing behind a dashboard or infotainment module where a straight plug would exceed the bend radius. ## Cable Compatibility and Termination Sequence The cable group is the first fit check: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 all share a nominal 0.195-inch dielectric diameter and a 0.106-inch center conductor, which matches the center contact bore and ferrule ID. The PTFE dielectric material handles the soldering heat without degrading the impedance match.","metaTitle":"FA1-NARJ-C04-0 FAKRA SMB Jack, Code A, 50 Ohm, 6 GHz","metaDescription":"FA1-NARJ-C04-0 FAKRA SMB jack, female socket, Code A keying, 50 Ohm impedance, DC-6 GHz, 0.3 dB insertion loss.
