Trig TT23 & TT23G transponders

The new TT23 series is the next generation of Trig’s compact Transponder line.
This new design features a smaller and lighter transceiver than its predecessors, while still boasting a nominal power output of 250 watts.
The TT23 is a two part transponder system, which includes an integrated altitude encoder. The TT23 is a Class 1 transponder. This means that you can use a TT23 if your plane is capable of flying above 15,000 feet or faster than 175 knots, VFR or IFR.
It comes in two versions:
TT23G: The TT23G has a built-in GPS receiver - the ideal choice for pilots seeking an integrated ADS-B Out solution. It is a perfect solution for enhancing conspicuity and safety.
TT23: The TT23 can also be used as an ADS-B out solution when connected to a compatible external GPS.
For those that do not intend to equip with ADS-B out, the TT23 model is a high- quality, modern transponder with easy configuration options that make it suitable for a broad range of GA applications.
