QUESTIONS & ANSWERS
The TA70 antenna is included as standard in a TN70 GPS kit. This simplifies compliance, as both the GPS and antenna meet the FAA 2020 mandate for ADS-B.
However, the TA70 is not included when purchasing a TN72. This is because uncertified pilots do not need a certified antenna.
The TA70 has a screw-on TNC connector.
WAAS, short for Wide Area Augmentation System, is a satellite-based augmentation system developed by the Federal Aviation Administration (FAA) to improve the accuracy, integrity, and availability of GPS signals for aviation purposes.
The primary goal of WAAS is to enhance the precision of GPS signals, particularly in critical applications such as aircraft navigation during approach, landing, and en-route phases. WAAS achieves this by using a network of ground-based reference stations and geostationary satellites to monitor GPS signals for errors caused by factors like atmospheric conditions and satellite geometry.
The Trig TA70 GPS antenna comes with a two-year warranty, starting from the day of installation. The warranty covers repair and/or replacement, at Trig’s option, of any parts found to be defective, provided such defects are deemed due to faulty material or workmanship and are not caused by tampering, abuse, or normal wear.
The TA70 is an active (amplified) antenna providing an average of 28.5 dB gain over a passive (non-amplified) antenna.
