Add to Wishlist
Part# 11-15210


The echoUAT is a Class B1S ADS-B UAT transmitter coupled with a dual-link 1090MHZ / UAT receiver. An integrated Wi-Fi system transmits traffic and weather to popular Electronic Flight-Bag (EFB) applications on iOS and Android, including ForeFlight Mobile. Direct interface support for common EFIS systems such as Dynon SkyView, GRT and MGL. A zero-install, internal wireless monitor decodes replies from legacy Mode C transponders for maximum retro-fit capability. Extensive position source compatibility, including the uAvionix SKYFYX GPS.

The echoUAT meets the performance requirements of 14 CFR 91.227.

SkyFYX combines a high precision WAAS GNSS sensor with an integrated RAIM processor. Resilient against jamming, spoofing and GPS range errors—SkyFYX provides reliable navigation in challenging environments. SkyFYX is the most affordable ADS-B rule-compliant position source companion for the echoUAT ADS-B transceiver.

The SkyFYX meets the performance requirements of 14 CFR 91.227. For use in Experimental and LSA aircraft.

Included with the echoUAT+SkyFYX-EXT bundle:
  • echoUAT ADS-B Transceiver
  • Wiring harness
  • SMA to BNC lead
  • UAT(978) antenna
  • SkyFYX-EXT All-in-One GPS Receiver and Antenna

Cost effective, small and not too cumbersome to install. Setup was straight forward and it worked on first try. Recommended for those who can.

Great product! Installed in my experimental and interfaces with my Garmin 320A perfectly for ADSB out. Never a glitch from the first day until now and all PAPR reports come back clean. Displays traffic & weather in on my iFly 740b and on my iPhone running the iFly app. Be certain to mount the antennas as given in the instructions and follow the setup menu carefully for a trouble free install.

Canadians may not require these but a few of us purchased these and are astounded how well they work. Easy install and now situational awareness is much improved. Of course cant see everyone but we are seeing many more planes than without this device. Thank you from Alberta

I thought spruce did a fine job.

Super easy install. Worked perfectly first time except Baro Press failed 7% of the time. Changed the Transponder Threshold from 1350 to 1200 and the next PAPR was perfect, no failures. ADS-B IN works great with Foreflight. This was a perfect solution for my Experimental Airplane.

The unit was the cheapest I could find and it works. I have not flown with it yet but it is programed and ready to go. I needed help with programing as it wouldnt accept the ICAO code and had to do a work around with the Ipad and then it went right in. Their support people were great!! It is installed in my Glasair 1, and is located in the fuselage as it is all glass. Delivery was overnight from CA to NV

Q: This says the UAVIONIX ECHOUAT BUNDLE meets the performance requirements of TSO-154c Class B1S. I'm guessing that means that it is not actually TSOd. Is this approved to install in certified aircraft? Are they hoping this would fall under a minor modification that could be signed off by a A&P?

This unit is intended for installation into experimental / light sport aircraft. It is not TSO'd for installation into a certificated aircraft and there are currently no plans for certification of this unit.

Q: Does the UAVIONIX bundle ECHOUAT display FIS/TIS data on the Garmin 696 via RS-232?

No, the Garmin 696 can only receive ADS-B data from other Garmin units. For TIS-A Traffic, it can receive data from a Garmin Mode S Transponder (GTX 330) and for TIS-B traffic and FIS-B Flight Information data , it can receive from a GDL 39.

Q: What items will I need to install into an experimental aircraft, that does have a mode c transponder, but does not have a WAAS GPS? I am confused by all of the different configurations.

This bundle allows you to keep your mode C transponder and output ADS-B. The Skyfx is a GPS receiver and antenna built in so you can use this if you do not have a GPS display.

Q: Will this work with a GTX330 transponder?

Per the manufacturer, yes it will.

Q: I have a Sandia 165 transponder, will the UAVionix EchoUAT unit interface with mt xpdr?

Yes. The echoUAT will communicate with Mode C transponders, so your STX 165 will work.

Q: So as I understand this bundle, If I have a transponder but no mode C, this will use the squak code and its own altitude information to broadcast all the ADS-b data. So I do not need mode C on my transponder for this to work correctly....Right??

This unit uses the MODE C or MODE S signal to output ADS-B data. The antenna will cover you for WAAS GPS signal.

Q: What is the length of the wire harness?

Per Uavionix the ECHOUAT comes with a 9ft harness.

Q: Will the gps receive a signal under poly fiber fabric like it does under fiberglass?

Per the manufacturer, if you are trying to place the antenna inside the poly fiber fabric it will continue to work.

Q: So this is for Experamental and LSA aircraft. Does this include certified light sport aircraft. Those of us with Vintage Sport AC - 1320 lbs. J3 & PA-11 Piper Cubs, Champs, Taylorcraft etc. With the small Continental engines A & C. -8 Without a place to mount a generator, all those that are NON -Electric But may have a battery & installed Communication Radio & Mode C trans. Some of us are so equipped, have a wind alter. It is a challenge to interpret the regulations. ACS could help a lot of us with uAvionix gear.

This is for experimental only, and cannot be used on certified aircraft.

Q: Will this Uavionix EchoUAT system qualify for the FAA rebate for ADSB systems?

No. Since this unit is not TSO approved, it does not qualify for the FAA rebate for ADS-B. Only certified installations qualify for the rebate.
