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.

Uavionix has outstanding Tech Support. I recently bought an echo-UAT with the GPS package from Aircraft Spruce. I was not able to get much support from our avionics shops locally, as they are far to busy to bother with my small project. David @ Uavionix was able to step me through the process from start to finish. My project was complicated, by the carbon fiber structure of the air frame. On top of the installation of the Echo, I was faced with multiple sources of noise through my avionics, radio, intercom and about everything else. With Davids experience he was able to help point me to some of the sources of the interference thereby guaranteeing a successful outcome of the ADS-B performance report. He went far beyond, which brings credit to the Support team and to Uavionix.

Haven’t installed this yet, but the instructions are easy to sort out and the units are very compact. Should be great.

Short version: Works. Gets data from my old Narco KT76A. Did the airborne performance monitor with no exceptions on the first try. Longer version: Box is very small and easy to mount – it has two status LEDs on the top, but you have to be right in line with them to see them (dim and recessed a bit). I got lucky with antenna placement since my transponder antenna is well aft so I ended up putting the ADS-B antenna under the pilot seat – kinda close to the landing gear, but seems to work. If my transponder had been further up front, then I would have needed to get a long cable fabricated. But, I mounted the box between the stick and the pilot seat so I was able to use the short (8 inch or so) SMA-BNC adapter cable that was supplied to connect to the antenna – however I had to get a male to male BNC adapter and a right angle adapter to get it all to work. The instructions say the minimum ground plane for the antenna should be 120 mm (4 3/4”) “per side”. I wasn’t clear if “per side” meant each side of a rectangle plate or each side of the antenna – the latter seems more likely. The biggest I could squeeze in between the tubes was about 12 inches square but it appears to work. I connected the power to the new breaker directly to the “line” input to the breaker for the KT-76A transponder to get the maximum common mode noise. Don’t know if that made any difference – but that’s what I did. Seems to pick up the transponder code / altitude without problems. The harness comes with all the wires in the connector. I tried to get the unused ones out by Micky Mouseing a tool – no luck – you probably would need the actual Molex tool – so I have three extra wires hanging out since I just used the Wi-Fi to connect to my Android tablet. Downloaded software and setup was pretty easy. SkyFYX-EXT was an easy install. Wires were plenty long. Easy to connect. No setup required.

Excellent product and customer support. Install was easy and straight forward. The built-in transponder monitor works well avoiding additional wiring to my Garmin GTX-327. Works great with FlyQ EFB app. Highly recommend this ADS-B transceiver.

Used the legacy installation (existing mode-C transponder) - straight forward. Works well. I use Foreflight App on iPad and no longer need the external GPS I had before - the uAvionix provides the location to the app also! Locks onto satellites very quickly. One caveat: If you operate near the Washington DC SFRA be aware that the FAAs ADS-B data for the 60 mile radius Speed reduction zone (Outside the TFR) causes the Foreflight App to treat it like an active TFR! (Youll get Approaching TFR and Inside TFR warning messages in that non-TFR zone) A really startling situation if you are not aware of this bug! It is NOT an App or hardware problem (as without the ADS-B it works correctly). I have been told that the FAA is aware of this but no correction is planned at the moment. Shouldnt be a problem for the rest of the country.

Have not completed the install, still working out the wiring details. The wires appear too short for my installation so will have to extend them. Will see how it works.

Grat product at a reasonable price. Easy ito install and simple to setup using the app downloaded on my tablet. Passed the FAA perforance test on the first flight after the install. Very happy with the results.

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.
