3.8 Antenna
3.8.1 Antenna Selection
Recommended antennas: see section 3.11 Accessories
Choose an antenna type compatible with the vehicle and the
mounting location.
Specified features depend on proper installation of the antenna.
The radiation pattern needs to be verified considering aircraft type
and mounting location.
The electrical interference between the antenna and any other
equipment must be taken into account in such a way that no
reduction of the performance of any other system will occur.
Install only certified antennas!
3.8.2 Installation Recommendation
Take note of the antenna manufacturer’s instructions.
The usually deployed Dipole- or Blade antennas necessarily
require a high frequency capable solid metal ground plane at the
antenna base.
For installation in composite aircrafts, ground planes are to be
added. The ground plane should be as large as possible but in any
case not smaller than 10 cm x 10 cm. If in doubt, please contact
the aircraft manufacturer.
Keep away three feet from any other antenna.
Pursue mounting in vertical position under the belly in flight
direction.
3.8.3 Antenna Wiring
Suitable antenna cables: see section 3.11 Accessories
Keep wiring as short as possible.
The smallest cable bend radius is 10cm. Avoid sharp bends.
Keep away from an ADF antenna cable at least 12 inches.
Electrical connections to the antenna shall be protected against
moisture to avoid loss of efficiency.
