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.
