TN70 / TA 70 kit – ADS-B, full compliance for certified types
If you’re an aircraft owner looking for a fully compliant ADS-B Out solution, (usually in mandated airspace) then the TN70/TN70A is the ideal partner for a Trig transponder.
Both GPS Position Sources are simple to install and provide a great way to add a certified FAA TSO-C145 WAAS GPS receiver to complete your ADS-B Out installation.
Free FAA ADS-B STCs are available for both TT22 and TT31 transponders. Customers requiring an STC and installing a TT31 transponder, must pair it with the TN70. Customers using a TT22 can select either a TN70 or TN70A, which is covered by both FAA ADS-B STCs.
Always check your local ADS-B regulations to ensure regulatory compliance.
