The TN72 GPS Position Source brings ADS-B Out capabilities to your Trig transponder. Light weight and easy to fit, the highly affordable TN72 uses certified technology making you visible to all ADS-B In traffic devices.

Flying in busy skies with a TN72 will reduce your risk of collision and improve flight safety. In the U.S. the TN72 used as your ADS-B Out solution will trigger a full traffic service uplink – received using ADS-B In equipment.

When using a TN72 there are two different ways to set up your Trig transponder (shown below). The TN72 hardware is the same in either installation.

TN72 GPS – X configuration uses SIL 3 in the transponder settings, and fully satisfies the technical requirements of FAR 91.227 for 2020 compliance. Light-sport, experimental and homebuilt pilots who have fitted a TN72 are now flying inside ADS-B airspace and have passed FAA compliance checks with flying colours.

TN72 GPS – TABS (Traffic Awareness Beacon System) configuration uses SIL 1 in the transponder settings. TABS is the FAA technical standard that enables voluntary equipage of ADS-B Out. The TN72 using TABS is ideal for certified gliders and Part 23 aircraft, operating outside of U.S. 2020 rule ADS-B airspace as a means of enhancing visibility and triggering traffic.

Installing a TN72 and suitable GPS antenna is a small price to pay for enhanced visibility and peace of mind.
