SMA Female to RP-SMA Male patch cables are very short coaxial cables.  They are designed to sit between a larger feeder cable and the end device thus providing flexibility and strain relief to prevent damage to the equipment.

The cable’s RP-SMA Male connector is designed to screw on to WiFi devices which use the Reverse-Polarity SMA interface type.

The SMA Female is a rear-mount bulkhead connector which in addition to connecting to the larger cable also allows integration of the patch cable into an enclosure or mounting frame.

The L-100 Patch Cable, RP-SMA Male to SMA Female is 18 cm (180 mm) in length.  It uses a high quality L-100 coaxial cable to permit operation on wireless devices through to 6 GHz.
