TT21 Product Design

Trig’s compact transponder is in two parts with a compact control head; this includes an inbuilt altitude encoder – saving further space and expense. A separate hardware box can be installed anywhere in the airframe. The mounted control head is only 54mm (2 3/25”) deep and can be fitted in panel using a 57mm (2 ¼”) round hole or smaller compact mount – the unit ships with the necessary fittings for both install options. Our compact transponders are highly efficient, whilst used in a wide range of GA types they are ideally suited for use in gliders and balloons, via an auxiliary battery.

Trig’s compact transponders are easy to operate and have a crisp, bright display that’s easy to read in all lighting conditions and is equipped with manual dimming. The transponder control head is splash proof too, so it’s ideal for open cockpit and seaplane operations.

Power Output and ADS-B

Trig’s TT21 has a 130 watts nominal power output, making it a class 2 transponder that meets international standards for 1090ES ADS-B Out (TSO C166b). The TT21 is ideal for use in flight where a light weight Mode S solution is required and is suitable for both IFR and VFR use.

Here's a question we get asked often:  If the transponder and GPS receiver are both TSO'd, why can't it be installed in a Part 23 certified aircraft?  Answer:  There is no AML STC available for this model transponder or GPS.  To install it in your Cessna 172, you would need to raise a local mod which would cost more than the installation.  But why can't I install it in accordance with AC43-14?  Answer:  AC43-14 Appendix 13.3.4 only allows the installation of systems that already have an AML STC for a similar aircraft.  Sorry guys, but for a Part 23 certified aircraft, you need the more expensive TT22 and TN70 combo.
