Compact and Lightweight

The ADS-B bundle installation options are versatile and practical. Each of the products within the bundle are lightweight and compact. The transponder hardware back box, and TN72 GPS can be installed away from your panel saving space and easing installation. The TC20 transponder control head includes a built in altitude encoder and can be installed in a 2 1/4″  round mount or in a space saving compact mount.

Already flying with Trig?

If you are already a Trig pilot and flying with a TT22 transponder, then adding a TN72 GPS position source and GPS Antenna to your installation will provide ADS-B Out. This is a simple installation and makes sense – you already have half the solution.

Alternative products

For installations where space is tight, we offer a highly compact puck GPS antenna called the TA50.  This is an uncertified, lightweight and discreet. The antenna cable is available in 100cm or 300cm lengths. If you would prefer this option then ask your dealer to order the TT22 transponder, TN72 GPS position source and a TA50 antenna individually.

Warranty and Support

All Trig products ship with a two year warranty, this starts from the date of installation not from the date of purchase.  All software updates are free from our Service Center (in Kansas Wichita) and the team can turn this around for you in five working days (excludes shipping costs).
