The insertion loss holds at 0.18 dB across the band, which means the connector contributes less than a fifth of a dB to the link budget at the top end of its range — a tight figure for a threaded interface at this frequency. It terminates to RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cable groups, so it covers the common 50 Ohm flexible and semi-rigid coax types used in antenna feeds, test equipment, and base-station jumpers. ## What ships in the box — and what doesn't need ordering separately The kit includes the gasket, lockwasher, and nut for the bulkhead mount. The contact and ferrule are crimp-terminated. ## Mating cycles and contact plating — reconnect life The nickel-plated brass body handles the environmental exposure on a bulkhead mount. The 031-2367-RFX is the male pin plug version of this same TNC series — same 50 Ohm impedance, same 11 GHz ceiling, same 0.18 dB insertion loss, same 500-cycle rating. The only decision-relevant difference is gender: the 031-2389-RFX is the jack (female socket) for a bulkhead-mounted receptacle, while the 031-2367-RFX is the plug for the cable end. No other spec changes between them.","metaTitle":"Amphenol RF 031-2389-RFX TNC Jack, 50 Ohm, 11 GHz, Bulkhead","metaDescription":"Amphenol RF 031-2389-RFX TNC jack, female socket, 50 Ohm, DC-11 GHz, 0.18 dB loss, 500 mating cycles.
