Instruments Designed For Small, Lightweight Installations

Jonker Sailplanes selects Becker Avionics' AR4201 Transceiver and ATC4401 Transponder to equip their JS-1 Racing sailplane. Jonker Sailplanes chose the Becker combination due to its small dimensions, light weight, low power consumption and outstanding performance.

The small and light-weight AR 4201 Transceiver offers 760 channels and is certified for use in VFR and IFR equipped aircraft. Even smaller and lighter than its forerunner - the AR3201 - it is intended for installation in gliders, motor gliders and small aircraft due to its low power requirement and 2 ¼ inch round panel cutout. New technology has made it possible to shorten the depth of the module, including the connector, to less than 9 inches. The equipment has an output of 5-7 Watts carrier (16 W PEP). A standby frequency and 99 presets can be easily programmed and recalled. The AR 4201 has an intercom, panel-lighting, voltage indicator, an AF-input as well as an automatic test-routine as standard functions. Two dynamic and two standard microphones can be connected without any alterations. The display shows the active frequency and either the standby frequency, the memory channel used or the supply voltage and also the external temperature (with the optional temperature sensor). All functions can be remotely operated using the RS-232 interface.

The ATC 4401 Transponder of the Becker Avionics Compact Line has been specifically designed for all aircraft and helicopter applications, where small dimensions, light weight, and low power consumption are essential. With the same look and similar size as the AR 4201 transceiver, the mounting behind the panel is very simple, with a 2 ¼ inch hole. The ATC 4401 is provided in two certified versions, the ATC 4401-250 with 250 Watt minimum transmit power and the ATC 4401-175 with 175 Watt minimum transmit power. Both versions have fully transistorized transmitters and certified according to JTSO and TSO regulations. The sunlight readable display is illuminated for night operations. In addition to the transponder code the display also shows the current flight level, if an encoding altimeter is connected and Mode-C is selected. The ATC 4401 operates from 9.5 to 32.2 V DC. This makes it suitable for almost every application in general aviation. A standard encoding altimeter or blind encoder can be connected.
