This adapter can be used to connect an antenna with an SMA Male Reverse Polarity connector to a PC with an SMA Female connector.
Typically this is used to connect one of our Wi-Fi antennas (e.g. the Wi-Fi component of the J-ID4GW combi antenna, which has an SMA Male RP connector) to one of our PCs, which usually have all SMA Female connectors regardless of what technology the connector is used for.
SMA Female Reverse Polarity (for connection to antenna)
SMA Male (for connection to PC)
