The reverse-polarity interface swaps the gender of the centre contact relative to a standard TNC — the plug carries the female socket, so it mates with an RP-TNC jack that has a male pin. This is a common configuration in Wi-Fi and ISM-band antenna feeds where the interface must prevent accidental mating with standard TNC equipment. The kit includes four pieces: the connector body, a crimp contact, a ferrule, and a sleeve. The contact termination and shield termination are both crimp-style, which means the centre contact and the braid are each compressed with a standard hex crimp tool — no solder required. ## Which Cables Fit the 122116RP? The 122116RP is specified for RG-174, RG-188A, RG-316, LMR-100, and M17/119-RG174 cable groups. These are 50 Ohm coax types used in short-jump antenna leads and pigtail assemblies. ## How the 122116RP Compares to Its Siblings The closest functional peer is the 122392RP, which is also an RP-TNC connector with the same 50 Ohm impedance, 11 GHz frequency rating, 0.18 dB insertion loss, and 500 mating cycles. The difference is in the connector gender and cable group: the 122116RP is a plug with a female socket for RG-174-class cables, while the 122392RP is a jack with a male pin for larger cables like Belden 9913 and LMR-400. If your BOM calls for an RP-TNC plug on a thin coax, the 122116RP is the correct match; the 122392RP serves the bulkhead or panel-mount side on a thicker feed line.","metaTitle":"Amphenol 122116RP RP-TNC Plug, 50 Ohm, 11 GHz","metaDescription":"Amphenol 122116RP RP-TNC plug, female socket, 50 Ohm, 11 GHz max, 0.18 dB insertion loss.
