Sandia STX 165R Remote Mode-C Transponder

 In our constant quest to provide more value and more features for our customers, MGL Avionics is proud to announce integration of the Sandia Aerospace STX 165R Remote Mode-C transponder with the following EFIS systems for Experimental and Light-Sport Aircraft: 
 

• MGL Avionics XTreme EFIS
• MGL Avionics Odyssey EFIS
• MGL Avionics Voyager EFIS
• MGL Avionics iEFIS Touchscreen EFIS

The STX 165R is a low weight, low cost, 200 Watt remote mount Mode-C transponder. Through just 2 data wires, the MGL Avionics EFIS is able to display transponder status, send encoded altitude to the STX 165R, control its mode (OFF/STBY/ON/ALT), adjust Squawk code and Ident.

We believe this is an elegant and affordable way of meeting the FAA transponder requirements in the US, where only Mode-C is required for recreational Part 91 flight. And, the ability to mount the transponder closer to its antenna and further away from other avionics in the aircraft is also an advantage for homebuilders trying to lay out a clean and interference-free panel.

In cases where traffic detection is required, MGL Avionics recommends pairing the Mode-C transponder with an ADS-B transceiver, since ADS-B traffic is available in many more areas than Mode-S TIS.

The STX 165R retails for approximately $1,550, making it a lower cost option than many transponders. It weighs 1.16 lbs, uses 200mA of power and has a small size: 3.5"H x 1.8"W x 6.9"L.
