Overview

Trig produces smart, affordable and future proof avionics. If you’re an aircraft owner looking for an affordable ADS-B Out solution with superior performance then Trig has the right ADS-B solution to get you equipped today.

If you already own a suitable Trig transponder then our TN70 kit is the easiest way to meet the mandate. The TN70 includes a certified WAAS GPS and companion WAAS GPS antenna, designed to enhance your aircraft via a simple install that will deliver excellent ADS-B Out performance. If you need a Trig transponder to complete your TN70 ADS-B solution, then simply add one of our class leading products certified to FAA TSO C166b, the latest ADS-B standard.

A Trig transponder is the hub of an ADS-B Out system, using ‘extended squitter’ to communicate with ground stations and suitably equipped aircraft. It’s worth remembering; if you intend to use ADS-B In to access ADS-B ground services (TIS-B and FIS-B) then a compliant ADS-B Out must be installed. A Trig transponder is an ideal way to ensure your ADS-B Out is compliant.

Trig transponders use 1090ES technology - the ICAO ‘International Standard.’ A Trig system not only gives freedom to travel but it also has superior capabilities, 1090ES is required above 18,000 feet so it’s suitable for use in a wider range of aircraft types than UAT. TN70 – WAAS GPS and WAAS antenna
A compliant ADS-B Out demands a certified position source that is totally dependable. The TN70 takes no panel space, it is fitted discretely as a stand-alone GPS so you can retain and use your existing panel equipment. The TN70 is paired with a high quality certified WAAS antenna optimised for our complete solution.

Installed recently and working well. Flight tested OK and qualified for FAA rebate. With my aircraft (Factory Great Lakes biplane), the Avionics shop was able to put the antenna inside the fuselage where it doesnt show.

Q&A

Q: Can I use the Trig TN70 ADS-B system with NARCO mode C transponders?

The Trig TN70 ADS-B system is designed to work with ADS-B capable Mode-S transponders.

Q: Regarding the Trig TN70 ADS-B system: Can a combined VHF GPS antenna be utilized? I have limited space.

No it cannot, as the GPS antenna for the TN 70 is certifed with the system.

Q: I have a garmin 327 transponder. Will I have to change my transponder?

Yes, the Trig TN-70 will only work with mode S transponders. We recommend the Trig TT21 (11-07999) to be used with the TN-70.

Q: Is the Trig TN-70 compatible with the Bendix/King KT-76A Xponder?

As of 7/6/15, the TN-70 is only compatible with Trig transponders. Please see part number 11-07997 for the TT31.

Q: Is the Trig TN-70 compatible with the Bendix-King KT74 Mode S Transponder which is made by Trig?

No, the software in the KT-74 is not made by Trig and is not compatible with the TN-70.

Q: Does the Trig TN70 ADS-B system have a NMEA 2400 output to use as an EFIS position source?

It only has two RS-232 ports, we do not see any NMEA 2400 output in the manual.

Q: What antenna is included with this system? Is an installation kit included?

A WAAS GPS antenna is included as well as a mating connector. The unit is flange mounted so no tray is required. You will need to supply the coax cable assembly between the receiver and antenna.

Q: Does the TN70 ADS-B system come with pins to connect to the TT-22?

Yes, it does.

Q: What is included in the custom harness for the Trig TN70?

It is a custom wiring harness for your specific installation. You specify which units you need interconnected and the distances and we prepare all the necessary wiring for you.

The Trig TN70 ADS-B system is designed to work with Trig products, we have no data to support that this will work with Garmin transponders.
