The Amphenol 132119RP is a reverse-polarity SMA (RP-SMA) jack with a male pin — the opposite gender arrangement from a standard SMA jack, which normally carries a female socket. The gold-plated brass body and PTFE dielectric suit outdoor or weather-exposed enclosures; the weatherproof rating means the interface seals when mated to a matching RP-SMA plug. It is part of Amphenol's 1321 series of RF coaxial connectors, and the 6-piece kit includes everything needed for a single cable termination: the connector body, a centre contact, a crimp ferrule, a heat shrink tube, a lockwasher, and a bulkhead nut.
This connector is built for RG-174, RG-188A, RG-316, LMR-100, and M17/119-RG174 cables — the common small-diameter 50 Ohm coax types used in Wi-Fi antennas, GPS receivers, and short-run RF interconnects. The shield terminates with a crimp ferrule; the centre conductor is soldered. The kit includes a heat shrink tube to seal the cable entry, which combined with the weatherproof rating makes this a field-ready assembly for outdoor antenna leads or bulkhead pass-throughs. The 500-cycle mating life is typical for SMA-class connectors and supports periodic disconnect for equipment servicing.
The 'RP' in 132119RP signals reverse polarity: this jack has a male centre pin instead of the female socket found on a standard SMA jack. It mates with an RP-SMA plug that has a female socket — the opposite of a standard SMA pair. If your antenna or cable assembly uses standard SMA, this connector will not mate. The threaded fastening is the same 1/4-36 UNS thread as standard SMA, so the coupling nut engages, but the centre contact gender mismatch prevents signal continuity. Check that your mating half is explicitly marked RP-SMA before specifying this part.
