BendixKing KT 74 ADS-B Out Transponder

ADS-B Out Transponder


The KT 74 is an ADS-B Out transponder that enables you to comply with the mandate to have ADS-B in your aircraft by January 1, 2020. It is a slide-in replacement for your existing KT 76 and KT 78 transponders. The KT 74 broadcasts on 1090 MHz, and can be expanded to also receive ADS-B In using UAT, providing you with weather and traffic information.



For owners that currently have a panel mounted WAAS GPS, the KT 74 is the most affordable option. KT 76 and KT 78 owners save even more as the KT 74 in a slide-in replacement for those transponders.



As a slide-in replacement for your existing transponder, no time is spent cutting your panel or mounting rack, replacing mounting trays or installing a new wiring harness. Within a few hours, your aircraft will be ADS-B compliant.



The KT 74 has a black powder-coated aluminum bezel and easy to read light blue LCD display to maintain the quality and feel you have come to expect with BendixKing.
