Operation and Installation

4.7.4.2 Auto-ON

Connector pin 20 determines the radio’s behaviour when applying power:
To activate the radio in aircraft with a dedicated avionic master switch by
this master (i.e. by applying power to the radio), connect pin 20 to the
avionic master

additionally

to pins 11 and 12; in this case, the radio’s

on/off-key has no functionality.
In aircraft without a dedicated avionic master, pin 20 is left open; in these
case, the radio’s on/off-key is used.

4.8 Antenna

4.8.1 Antenna Selection

•

A VHF-COM-Antenna with an impedance of 50 Ohm is required.

•

Choose an antenna type approved for the aircraft and the mounting

location.

•

The antenna should be located far away from ELT-antennas and

other VHF antennas.

•

Specified features depend on proper installation of the antenna.

4.8.2 Installation Recommendation

•

Take note of the antenna manufacturer’s instructions.

•

The metallic contact between airplane surface and antenna-GND

must be very good. On non-metallic airplanes a metal foil (min. 80 cm
x 80 cm) shall be used as electrical counterweight on the inside of the
belly.
