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.
