Easy Installation

  • Installation is as simple as replacing the aft aircraft position light.
  • No airframe modifications or additional antennas are required.
  • Works with any Mode C or Mode S transponder.
  • Transponder data is provided via the existing aircraft wiring system using the Power Transcoder.
  • TailBeacon uses the existing mounting location, breaker, and wiring.
  • The installation requires 2 screws and reuses the existing power and ground to your current position light.

Goof-Proof Configuration

Mechanically installing an ADS-B solution is only half the battle. The skyBeacon mobile application can also be used to configure tailBeacon. The intuitive, easy to use app guides you through setting the necessary values including the ICAO address, emitter type, aircraft length, width and GPS offsets. Since tailBeacon is self-contained there are no serial ports settings or protocols to configure.

The skyBeacon mobile application is available for both Apple iOS and Android.


This is a great product. I have installed 2, so far. It is STCd for the Cessna 172. I am a qualified installer for uavionix. If your A&P needs support from an IA who is comfortable with the product regarding installation on other models, Gmail me at a9548925559

Installation (TSO version) took 30 minutes, including time needed to install Whelen type 2 pin plug on TailBeacon wire leads for a factory connection to the Position Light power plug on the Beechcraft. Setting the parameters took another 30 minutes. The ground check was done in 20 minutes, followed by a 30 minute flight check. No removing of interior side panels, floor, ceiling, or seats to route antenna or power cables. No modifications to the instrument panel. The uAvionix TailBeacon is an excellent solution to meet the Jan 1st FAA compliance requirement.

The staff in Corona were very helpful. They back ordered this for me since my rebate was expiring soon, it showed up a few days later and they called immediately. Installation was a breeze and setup was very easy. Passed validation flight on the first attempt. Note you may have to adjust the setting to read the transponder squawk code. Test it with various configurations of power draws and engine on/off to verify its consistently reading. Im happy I waited for this to come out. Note, after you submit for your rebate youll need to email the FAA rebate help line with a photo of your invoice/sn proving you bought the TSO version.

One well made unit. This is a very good solution to the ADSB mandate.

We have installed two of these units in experimental aircraft and they work perfectly. Installation and setup was easy in those aircraft so we expect no difference with the certified unit. In our opinion the most resoneable solution to the ADS-B requirement.

Spruce folks were very helpful with this order, especially given that I was on a tight schedule to meet ADS-B rebate requirements.
