Trig Avionics produces the TT31 transponder, a 'plug and play' retrofit that's ADS-B capable and replaces old Bendix KT76A, KT76C and KT78A transponders.

Trig also produces the TT22, a compact ADS-B capable transponder, designed to save space in the panel. Both transponders are class 1 devices and meet the 2020 ADS-B mandate.

Aircraft owners contemplating the merits of a Trig transponder can now take advantage of Trig's complimentary TN70 WAAS GPS and antenna. This provides a C145 compliant GPS source for a TT22 or TT31 transponder. The TN70 price has been cut and is now available at a list price of $ 1,975.

Trig's Marketing Manager Jon Roper said, “With the FAA Rebate available we have reduced the price of the TN70. This means you can now secure a complete ADS-B Out system from only $ 3,763.” This superb package includes a TT22 Mode S transponder and TN70 WAAS GPS system.

The TN70 is a blind GPS unit, installed away from the panel; the pilot can continue to use an existing non WAAS navigator without disruption. Alternatively, aircraft owners with Garmin GNS or GTN WAAS navigators can use Trig’s FAA ADS-B STC that covers both TT31 and TT22 transponders and has an STC AML list covering hundreds of airplane models. The STC is free and a custom PMA parts kit for air ground determination in Part 23 aircraft costs just $ 100.00.

Trig is a UK company with an extensive US dealer network and a US based service center at Mid Continent Instruments and Avionics.
