The RP-TNC interface swaps the center contact gender versus standard TNC, making it the correct plug for Wi-Fi access points, ISM-band radios, and antenna feeds that specify reverse-polarity connectors. Rated at 50 Ohm impedance with a maximum frequency of 11 GHz, it covers 2.4/5 GHz Wi-Fi, 900 MHz ISM, and L-band GPS applications without issue. This connector is listed for RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cables — a broad set covering the most common 50 Ohm flexible and low-loss coax types used in short- to medium-run RF links. Both the shield and center contact terminate via crimp, which is the standard field method for these cable groups. The included ferrule compresses over the cable jacket, and the center contact crimps onto the center conductor. ## Construction and Environmental Range The threaded fastening type ensures a vibration-resistant mate when torqued to the mating jack. Insertion loss is specified at 0.18 dB, which is typical for a TNC-class interface at these frequencies and represents minimal signal attenuation per mated pair.","metaTitle":"Amphenol 122108RP RP-TNC Plug, 50 Ohm, 11 GHz, 500 V","metaDescription":"Amphenol 122108RP RP-TNC plug, female socket, 50 Ohm, 11 GHz, 500 V.
