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.
The TN70A model is technically identical in terms of GPS performance, certification, size and form factor to the TN70, it was introduced when the TN70 version was unavailable in 2022. The TN70A part number is 02466-00, it ships with a TA70 GPS antenna in a kit, in exactly the same way as the TN70.
Free FAA ADS-B STCs are available for TT22 and TT31 transponders. Please note 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.
