TN72 ADS-B Bundles
If you are looking for a complete Mode S and ADS-B Out system, then you need one of our TN72 Bundles.
There are two different TN72 ADS-B Bundles available – choose the one that suits your requirements.
TT21/TN72 Conspicuity Bundle – ideal for flight below 15,000 feet where a Class 2 transponder is permissible for Mode S and ADS-B Out. The TN72 and TT21 in combination can be configured to either support TABS (SIL 1) or X configuration (SIL3) in the controller.
- 1 x TT21 – Mode-S, 1090ES, certified compact transponder (Class 2)
- 1 x TN72 – certified GPS position source
- 1 x TA50 – compact antenna with 1m lead and QMA connector (plugs into TN72)
TT22/TN72 ADS-B Bundle – select this if you operate a light-sport, experimental or home built aircraft in North America and you wish to be ADS-B Out equipped to fly in 2020 rule ADS-B airspace. This is a 14 CFR 91.227 compliant solution for these particular aircraft types. The FAA require you to have a Class 1 transponder (the TT22).
This configuration also best suits high performance aircraft and those operating above 15,000 feet.
This kit includes:
- 1 x TT22 – Mode-S, 1090ES, certified compact transponder (Class 1 required)
- 1 x TN72 – 14 CFR 91.227 compliant certified GPS position source
- 1 x TA70 – certified WAAS GPS Antenna
It is possible to purchase items separately – please contact your nearest Approved Trig Dealer to make your aircraft ADS-B Out visible and improve your flight safety.
Compact and Lightweight
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 TT21 or TT22 transponder, then adding a TN72 GPS position source and GPS Antenna to your installation will provide ADS-B Out. This makes sense, as you already have half the solution.
For installations where space is tight, the highly compact puck GPS antenna, the TA50 is ideal. This is an uncertified antenna, it is lightweight and very discreet, the cable is available in 100cm or 300cm lengths. Every product can be purchased individually, but bundles make a one box solution attractive.
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 Trig Service Centres (excludes shipping costs).

Frequently Asked Questions
Does the bundle come with all relevant wiring?
To make your installation easier Trig wiring harnesses are available, to purchase as an extra accessory. Trig transponder wiring harnesses are available in 100cm or 300cm lengths and come with or without a connector to the TN72. Due to the variety of options available we advise you to select the most suitable wiring harness from our wiring harness product page (found in the left hand 'Product' navigation menu).
I am flying outside the US and would like to purchase the bundle. How can I do this?
In most cases you should consider the TT21/TN72 Conspicuity Bundle. The T22/TN72 ADS-B Bundle is popular in the US. In the US to be ADS-B complaint you must use a TT22 (Class 1 transponder). Outside of America you can you use the TT21 (Class 2 transponder). Check your local / appropriate ADS-B regulations to verify if a Class 1 transponder or Class 2 transponder is required?
Does Trig offer a highly compact GPS antenna?
In installations where space is at a premium, for example in gliders or ultralights, we offer a highly compact puck GPS antenna called the TA50. This is an uncertified, lightweight and discreet solution. The antenna is available in 100cm and 300cm cable lengths.
If you would prefer this option then ask your Dealer to order the TT22 transponder, TN72 GPS position source and TA50 antenna individually.
