The QMA from Anoison Electronics is a Quick Locking SMA connector that exhibits electronic performance equivalent to the SMA up to 18 GHz. Completely intermateable with other QMA designs currently on the market, Anoison's QMA series distinguishes itself by way of its waterproof seal (IP68) and a streamlining of its internal construction that results in significantly fewer raw materials necessary for manufacture.

This is in addition to 10x faster mating/de-mating than the traditional SMA, denser packaging because a torque wrench is no longer required for intallation and greater flexibility since the connector may be rotated 360 degrees while in the mated postion.
