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 Antenna Cable

The antenna is connected by a 50 Ohm coaxial cable. The
connection to the radio requires a male BNC connector.

4.8.3 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.

•

To avoid a mutual interference of the radios, the antenna isolation

between a voice transmission and a navigation antenna as well as
between double COM antennas should be as large as possible. A
distance of 2 meters usually is sufficient.

The cable length, the attenuation of the selected cable and
the quality of the connections has a direct effect on the
transmitted power at the antenna. For support please
contact your maintenance organization.
