That detail matters when you're grabbing a connector for a radio or antenna port that uses RP-TNC — standard TNC won't thread on. Shield termination is crimp; the centre conductor is soldered. Rated 500 mating cycles — that's field-service grade. You can reconnect antennas or test cables several hundred times before the gold plating on the centre contact wears enough to shift contact resistance. The threaded fastening keeps the pair locked under vibration, which is why TNC is common in mobile and industrial RF links. ## What Crosses to This Connector — 122392RP for Larger Cable The other peer, 122168, is a standard TNC jack (not reverse-polarity) with a bulkhead mount — that's a different connector family for panel-feed applications. It won't mate with an RP-TNC port, so it's not a cross-shop candidate. The 122140RP is listed as Active on the manufacturer's lifecycle status.","metaTitle":"Amphenol RF 122140RP RP-TNC Plug, 50 Ohm, 6 GHz, Bulk","metaDescription":"Amphenol RF 122140RP RP-TNC plug, female socket, 50 Ohm, 6 GHz max, 500 V.
