This adapter is used to enable cables and antennas terminating with an RP-SMA Male to connect to standard SMA equipment.

As a result of US FCC regulation WiFi devices always use Reverse Polarity SMA (RP-SMA), which has a male pin protruding from the threaded female body. RF cables supplied for WiFi equipment will use an RP-SMA Male connector, resulting in two female sockets unable to interface. This adapter threads into the RP-SMA Male cable and allows connection to ordinary SMA devices.

This model has an extended operating frequency range to 6 GHz, covering sub-6 GHz wireless applications such as n/ac/ax WiFi and multipoint networking.
