RP-SMA Male to SMA Female Adapter
This is an adapter that converts an RP-SMA board to an SMA antenna. The adapter will connect to a device with an RP-SMA antenna connection (like SenseCAP gateways) and will allow you to use an antenna/cable with an SMA connection.
Note: Most gateways/devices have SMA antenna connection.
