The ATU-20X is a remotely mounted ADS-B transceiver.  It incorporates a dual-link (1090 MHz and 978 MHz) receiver and 978 MHz UAT Class B1S transmitter.  ATU-20X features a direct wired communication for use with popular EFIS from Dynon, GRT and MGL Avionics.  An integrated Wi-Fi access point also supports many popular EFB applications on iOS and Android.

ATU-20X is designed to use the aircraft’s existing altitude encoder and ADS-B compliant GPS position source. The uAvionix FYX GPS can be used in the event your EFIS manufacturer does not supply one.

A zero-install, internal wireless monitor decodes replies from legacy Mode C transponders for maximum retrofit capability.

The Echo ATU-20X is designed to meet the performance requirements of TSO-C154c, and is compliant with FAR 91.227 for operation in the National Airspace System.
