The newly developed KTX2 is a super-light, compact, mode-S, 2020 mandate (ADS-B Out) compliant transponder with low power consumption and a high-end TFT color display.

As a Class 1 transponder with an operating range of up to 30.000 ft. and 250 knots, it is ideal for all GA aircraft, including gliders, experimentals, ultralights and balloons, VFR and IFR. The KTX2 provides maximum possible safety, since in addition to the Squawk, the unit also transmits the flight level and a unique 24-bit identifier which is allocated to the particular aircraft. Furthermore, air traffic control is able to send requests to particular transponders. With this, the KTX2 makes a remarkable contribution toward flight safety.

The KTX2 is currently available in two versions: The standard version for installation in a 57 mm / 21” round cut out and the 160 mm / 61” stack version. A housing length of only 146.2 mm for Standard format means that the transponder can even be installed quite easily in cockpits with difficult space restrictions.
