RP-SMA Female to SMA Male RF Adapter

Quantity One. A description of the RP-SMA connector from Wikipedia is below:

"Reverse-polarity SMA (RP-SMA or RSMA) is a variation of the SMA connector specification which reverses the gender of the interface. The term "reverse polarity" here refers only to the gender of the connector's contact pin, not in any way to the signal polarity.

The female RP-SMA connector has the same external housing as a standard or conventional female SMA connector, which consists of an outer shell with the threads on the outside; however, the center receptacle is replaced by a male pin."
