echoUAT from uAvionix

Affordable company ADS-B IN and OUT. echoUAT is a remotely mounted ADS-B transceiver that provides 2020 compliance ADS-B OUT, and ADS-B IN traffic and weather to your EFIS and iPad for the same cost as ADS-B receive-only solutions.

Bring New Life to Your Existing Panel

While other companies are looking to cash in on the ADS-B mandate by selling you a new transponder and WAAS GPS, uAvionix is taking a different approach. echoUAT works with your existing avionics, allowing you to put your savings in the fuel tank instead of additional costly avionics.
  • Keep your Mode C transponder
  • Use your existing WAAS GPS
  • Traffic and Weather to your existing supported EFIS
  • Support for popular iPad and Android Apps

Works with Your Existing Mode C Transponder

Already have a KT76A, Narco or Garmin Mode C? With the echoUAT integrated power transcoder, there is no need to replace your existing transponder. The power transcoder decodes squawk and pressure altitude by sensing pulses in the aircraft electrical system. Mode transponders require a wired connection to echoUAT. 

What about Apollo, Becker, Funkwerk, Microair or Terra? Yes, those work too.

Use Your Existing WAAS GPS

EchoUAT works with your existing WAAS GPS.  Fewer antennas to mount, less equipment to install and more value from your existing panel.

Currently supported GPS:

  • GRT Safe-Fly 2020
  • Garmin 400W series
  • Garmin 500W series
  • Garmin GTN series
  • Avidyne ADS-B+
