Bundle and save: iFly 740b  +  uAvionix ECHO Dual-Band ADS-B Transceiver

Struggling to see complex and confusing In-Air Weather and Traffic can be a thing of the past for pilots with the new iFly 740b GPS / echoUAT ADS-B bundle presented by Adventure Pilot and uAvionix, two industry leaders of high-value and simple-to-use aviation devices.  Pilots may choose from an iFly 740b and echoUAT with skyFYX or skyFYX-EXT GPS source. 

The iFly 740b and echoUAT Transceiver Bundle allows pilots to eliminate the guess work with full ADS-B Weather and Traffic on a dedicated and extremely sunlight readable aviation GPS, the iFly 740. 

The iFly 740b GPS boasts one of the brightest touchscreens on the market and the highest compatibility rates by supporting many of the ADS-B devices. All this on a market where a multitude of portable ADS-B devices are limited to a specific App or brand GPS.  

(Note: Any returns on either the echoUAT Transceiver or the iFly 740 will result in the loss of the Bundle discount, since the bundle requirements would no longer be applicable.)

UAT ADS-B Transceiver for Light Sport and Experimental Aircraft


The echoUAT 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.  EchoUAT 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.

EchoUAT is designed to use the aircraft’s existing altitude encoder and ADS-B compliant GPS position source. The uAvionix SkyFYX 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 UAT is designed to meet the performance requirements of TSO-C154c, and is compliant with FAR 91.227 for operation in the National Airspace System.


  • UAT Transmitter. Meets the performance requirements of TSO-154c Class B1S.

  • Dual-Link ADS-B receiver. Receives legacy 1090MHz ADS-B traffic and UAT traffic and uplink data. Meets the MOPs of DO-260B and DO-282B.

  • Integrated Wi-Fi to transmit In-flight weather, NEXRAD radar, METARs, TAFs, TFRs, AIRMETs, SIGMETs and NOTAMS to EFB applications.

  • Traffic information from both UAT and 1090ES provide a view of nearby aircraft

Transponder Reply Monitor

1090MHz Mode A and Mode C

Do I have to mount a bunch of antennas on my plane exterior?

No, unlike some competitors, the echoUAT use a single UAT/1090 antenna for Transmit/Receive and Receive.  You will need to mount the UAT In/Out antenna and a GPS antenna if you do not already have a compliant GPS source.  


Will I be able to see weather and traffic on my iFly Device or App?

Yes, the echo transmits weather and traffic on the commonly used GDL90 data format to ensure support for most iOS and Android Apps via WiFi.


Do I need to upgrade or replace my existing Transponder to use the echoUAT?

A. No, the echo has a built in no-install transponder monitor that works with most legacy Mode C transponders. That means no extra workload for you in the cockpit.  (It also supports direct integration with Dynon SkyView and many MGL and GRT EFIS models.)


Does echoUAT meet the 2020 mandate?

Yes, echo does meet the FAA’s 2020 ADS-B mandate for Experimental and Light Sport Aircraft when paired with a suitable GPS position source such as SkyFYX or a 2020 compliant GPS provided by your EFIS manufacturer.


Will the echo work with my Dynon Skyview?

Yes, the echoUAT can be configured directly through the Dynon Skyview display to provide:

  • Configuration of Echo through the EFIS
  • GPS data
  • Pressure Altitude Information
  • Current Transponder Squawk
  • ADS-B traffic display


Does my GRT EFIS support echoUAT?

Yes, the echo is designed to work with the GRT EFIS allowing the EFIS to provide:

  • Configuration of Echo through the EFIS
  • GPS data
  • Pressure Altitude Information
  • Current Transponder Squawk
  • ADS-B traffic display

Will the echoUAT work with my MGL EFIS?

Yes, the echo is designed to work with the MGL EFIS and has the following features:

  • Configuration of Echo through the EFIS
  • GPS data
  • Pressure Altitude Information
  • Current Transponder Squawk
  • ADS-B traffic display
