Trig TT21 Mode S Transponder – Minimum Panel Space and Maximum Benefit
Chosen by pilots around the world Trig’s TT21 compact transponder fits in the tightest panel space. The TT21’s innovative design saves both space and weight whilst delivering certified performance.
Customers in the U.S. should be aware that FAA, Federal Aviation Regulations (FAR) 91.227 requires that a compliant ADS-B Out solution use a Class 1 transponder. 1 is a Class 1 device and meets this requirement. The TT21 is a Class 2 device and does not meet this regulation.” The FAA has stated that Class 1 transponders must be used to be 2020 compliant. For this reason, we recommended the 1 unit if ADS-B compliance is required.

Product Design
Trig TT21 compact transponder comes in two parts – a compact control head that includes a built-in altitude encoder, saving further space and expense. A separate hardware box can be installed anywhere in the airframe.
The mounted control head takes up the minimal depth in the panel and can be fitted using a 2 ¼” round hole or smaller compact mount – the unit ships with the necessary fittings for both installation options. Trig’s compact transponders are simple to operate and feature a crisp, bright display – easy to read in all lighting conditions and equipped with manual dimming. The transponder control head is splash-proof too, so it’s ideal for open cockpit and seaplane operations.
One-handed operation is easy; the superior interface allows the rapid selection of Squawk code. A single press VFR button and ident button further eases operation. The display also features your tail number and flight level for ease of reference.
