Looking for a full-featured transponder in a small package? Sandia Aerospace’s newly certified STX 165 fits that bill. At fewer than 2 pounds, and only 3.5 by 1.75 by 7 inches, it can fit into almost any panel.
The STX 165 has both Mode A and Mode C capability. It also features three different timers, and a pressure altitude display. An optional probe is available to display outside air temperature, density altitude, and an icing alert.
The STX 165 is available for an introductory price of $1,700. Contact Sandia for more information.
