Dittel KTX2 Transponder

The Dittel KTX2 Transponder

The newly developed Mode-S Transponder KTX2 incorporates latest technology – The result is a highly efficient airborne equipment, offering lowest possible power consumption, smallest dimensions and lowest weight. As a Class 1 Transponder with an operational range up to 35.000ft and 250kt the KTX2 is ideal not only for microlight aircraft and gliders, but also for a major part of aircraft of general aviation up to 12500lbs MTOW (VFR and IFR).

PLAY SAFE – with the Dittel innovative model S KTX2 transponder

The fully re-engineered KTX2 is a super light weight, compact model S transponder with low current consumption and a premium TFT-colour display. Regardless of whether it is used in sport, microlight aircraft, gliders or balloons – the KTX2 offers maximum possible safety due to provision of precise position and ID-data for the air traffic control and other air traffic participants. As a result, the KTX2 is a reliable device to prevent collisions.

Advantages at a glance

  • Sensational low weight of only 360 grams (0.79lb) – ideal not only for gliders and microlight aircraft
  • Smallest dimensions – for an easy and flexible installation
  • Minimal current consumption – ideal for battery-operation in gliders and balloons
  • Large, high-contrast, durable TFT colour display for best readability even under direct sunlight
  • Intuitive handling – developed from pilots for pilots
  • Excellent cost-to-performance ratio

Easy, flexible installation

The KTX2 is available in three models. Beside the standard version for installation in a Ø57mm (2¼“) round slot, there is also a ‘mini’-version (which will be certified shortly) in landscape or portrait shaped housing. Due to a housing length of only 144mm (5-2/3”) the transponder can easily be installed in cockpits where there is limited space. For mobile use, e.g. on balloons, the KTX2 is available as a portable station – ideally in combination with the Dittel KRT2 radio transceiver in the same design.

  • Standard: 144 x 63,5 x 62 mm
  • Mini Landscape: 144 x 63 x 46 mm
  • Mini Portrait: 144 x 46 x 63 mm

Future proof features

The housing of the KTX2 is full of the finest technology:

  • Built-in high-precision, temperature compensated altitude encoder to connect to the static port
  • The hardware of the KTX2 is designed to deliver precise position data (extended squitter) for ADS-B.
  • Via the RS232 interface, an appropriate GPS receiver can be connected (supplemental ETSO-C166b certification in preparation)
  • Possibility of firmware upgrades
