[QMAConnector QMA-Connectors] are quick-connect versions of [SMAConnector SMA-Connectors], providing identical performance up to 6 GHz over 50 Ohm cable.

[QMAConnector QMA] provides many advantages over [SMAConnector SMA], since it mates with a click-on connection. This connection allows it to maintain full connection while being able to rotate 360-degrees. [QMAConnector QMA-Connectors] are more convenient for mobile use (since there is no requirement for clearance to spin a threaded connector), and often have a longer life-time.

Unfortunately, [QMAConnector QMA-Connectors] are rare on [WLAN] equipment outside of Asia due to [FCC] requirements in the USA.
