Benefits
Product Design
All Trig compact transponders are made up of two main parts: a compact control head with a built-in altitude encoder, saving both space and cost, and a separate hardware box that can be installed anywhere on the airframe. The control head is just 54mm (2 3/25”) deep and fits in a panel with a 57mm (2 ¼”) round hole or a smaller compact mount – it comes with all the necessary fittings for either installation option. Our compact transponders are highly efficient, while commonly used in various general aviation aircraft, they are particularly well-suited for gliders and balloons when paired with an auxiliary battery.
Trig’s compact transponders are easy to use, offering a clear, bright display that is easy to read in any lighting condition and can be manually dimmed. The control head is also splash-proof, making it an excellent choice for open cockpit and seaplane operations.
Power Output and ADS-B
The Trig TT23/TT23G has 250 watts nominal power output, which makes it a class 1 transponder and meets international standards for 1090ES ADS-B Out (TSO C166b).
Compatible Trig products
ADS-B enhances safety and visibility – your investment in a TT23 transponder is future proof. Trig has a matching certified GPS position source that is highly affordable called the TN72. This is ideal for ADS-B voluntary equipage. The TN72 can even be used to meet the 2020 mandate by light-sport, experimental and homebuilt types in the U.S.
Our TN70 GPS position source is suitable for certified Part 23 aircraft that need a TSO-C145 position source, for operations in 2020 rule ADS-B airspace using a TT22 transponder.
Both the TT23 and TT23G are suitable for customers in the U.S. who follow FAA 14 CFR 91.227 that requires a compliant ADS-B Out solution using a Class 1 transponder.
