The gold plating on both the body and the center contact keeps insertion loss stable over repeated matings in corrosive or outdoor environments. ## SMA vs RP-SMA — What This Adapter Solves Standard SMA connectors have a male pin on the plug and a female socket on the jack. Reverse-polarity SMA (RP-SMA) swaps the gender: the plug has a female socket and the jack has a male pin. The 132171RP takes a standard SMA plug (male pin) and converts it to an RP-SMA jack (male pin), so you can mate a standard SMA male cable to an RP-SMA female device (common on Wi-Fi access points and antennas). The threaded, threaded fastening on both ends provides vibration-resistant coupling. The 132171RP is the straight, male-to-male center gender version. The 132172RP is a right-angle body with the same conversion.","metaTitle":"132171RP SMA to RP-SMA Adapter, 50 Ohm, 18 GHz, Straight","metaDescription":"132171RP SMA plug to RP-SMA jack adapter, 50 Ohm impedance, DC to 18 GHz.
