The Amphenol 202117RP is a reverse-polarity TNC (RP-TNC) plug with a female socket center contact, built for 50 Ohm coaxial cable systems. The RP-TNC swaps the gender of the standard TNC interface — the center contact is a socket rather than a pin, and the coupling nut threads onto a male-threaded jack. This configuration is common in Wi-Fi access points and ISM-band equipment where the interface polarity prevents mating with standard TNC antennas. The plug uses a PTFE dielectric for stable RF characteristics and a gold-plated phosphor bronze contact for consistent signal transfer over repeated connect-disconnect cycles. The nickel-plated brass body handles the mechanical and environmental duty of field-installed cable runs.
