It is a single-port, female-socket connector with a threaded coupling nut for vibration-resistant mating. ## Mechanical and Installation Mounts through a panel with a bulkhead rear-side nut — the lockwasher and nut are included in the package (3 pieces: connector, lockwasher, nut). The shield is terminated via solder cup; the centre contact also terminates via solder cup. The isolated feature indicates the connector body is electrically isolated from the panel ground, which is typical for antenna feeds or floating-ground installations where a DC path to chassis must be avoided. ## RF Performance and Mating Cycles Rated insertion loss is 0.18 dB across the band up to 11 GHz. The threaded fastening type (TNC) provides a more secure mate than the bayonet-lock BNC of the sibling 031-10-RFXG1, which is rated to 4 GHz. If the application requires DC continuity through the connector at frequencies above 4 GHz, the TNC 031-4805-RFXG is the correct choice over the BNC variant.","metaTitle":"Amphenol RF 031-4805-RFXG TNC Receptacle, 50 Ohm, 11 GHz","metaDescription":"Amphenol RF 031-4805-RFXG TNC bulkhead receptacle, 50 Ohm, 11 GHz, gold-plated centre contact, 500 mating cycles.
