DeutschMode-S Transponder TRIG TT21 - Class 2
Trig makes the world’s smallest and lightest Mode S certified GA transponders. The TT21 Trig compact transponder can fit into to the tightest panel space. This allows other instrumentation or avionics to be accommodated, providing a genuine benefit in any installation.
The TT21 is a high powered performer, a Class 2 transponder – ideal for use in aircraft flying up to 15,000 feet and hot faster than 175 knots. It is also suitable for ADS-B, where a Class 2 transponder is required (within the U.S. for example). A free FAA STC allows the TT21 to be installed as a compliant ADS-B Out solution in 576 aircraft types. The TT21 is compatible with many popular GPS position sources including Garmin GNS and GTN navigators and the Trig TN70 – for further information see our U.S. ADS-B page.
