The TA14 is a certified transponder blade antenna, designed to partner with any Trig transponder. The TA14 provides optimum performance for our transponders and is suitable for both conventional GA and high performance aircraft types, up to 350mph and 50,000 feet. The TA14 antenna is a streamlined design and features longer mounting screws – this offers greater installation flexibility for both metal skinned and composite aircraft. Make your Trig transponder installation complete by adding a TA14.
