The STX 165 is a panel mount unit that uses a 1/2 3ATI panel cutout. Behind the panel depth is only 6 1/4” (not including connectors). With a built in Altitude encoder, installation time and cost is greatly reduced. The optional OAT Probe input provides additional capability including density altitude and OAT displays and icing alerts.

The STX 165 elevates transponder capability to a new level while reducing both weight and size. The solid state transmitter design provides 200 Watts nominal output with no warm up time. And because it’s all solid state, power requirements are at an absolute minimum.

  • Pressure Altitude Display: See what altitude your transponder is reporting to Center
  • Optional OAT Probe Input: Displays Outside Air Temp.,Density Altitude, Icing Alert
