This is a great connector for anyone doing RF work, when a straight SMA connector is required. Solder it into your PCB for a very secure mechanical connection. You've probably seen tons of these on various development boards! The four mechanical connectors also act as the RF ground.

Mates with any SMA plug. Check if you have RP-SMA or SMA by looking at the middle pin of your antenna/cable and verifying it will match with this connector!
