Becker AR4201 radio

The Becker AR 4201 aircraft radio is an extremely small and lightweight transceiver that offers 760 channels and is certified for use in VFR and IFR equipped aircraft. The clear, sunlight readable LCD 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). The AR 4201 radio is ideal for installation in gliders, motor gliders and small aircraft due to its low power requirement and 2 1/4 inch round panel cutout. Due to the implementation of the most modern technology it has been possible to minimize the depth of the module, including the connector, to less than 9 inches. The equipment has an output of 5 to 7 Watts carrier (16 W PEP). A standby frequency and 99 memories can be easily programmed and recalled. The AR 4201 has intercom, panel-lighting, voltage indicator, an AF-input as well as an automatic test-routine as standard functions. The Becker AR4201 radio is TSO'd and can be installed in certified aircraft.

Becker ATC4401 transponder

The Becker ATC 4401 transponder is a full solid-state transponder that has been designed as a part of the Becker Compact Line for all aircraft and helicopters where small dimensions and light weight are essential. It has the same look and similar size as the successful AR 4201 transceiver. The mounting behind the panel is as simple as for the AR 4201. This transponder offers outstanding performance combined with low power consumption and this transponder is provided in two certified versions...
                ATC 4401-175 with min. 175 Watt transmit power
                ATC 4401-250 with min. 250 Watt transmit power
Both transponder versions are state of the art designs with fully transistorized transmitters and compliant with the current, most stringent operating standards. The ATC 4401 is certified according JTSO and TSO regulations. The sunlight readable display is illuminated for night operations. The display shows in addition to the transponder code also the current flight level, if an encoding altimeter is connected and Mode-C is selected. Despite the small size, the operation is simple and straight forward. It even allows the one button recall of two preselected codes. 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.
