6.5 ANTENNA INSTALLATION
Locate a position where the antenna can be installed vertically (up to 15 o off the vertical plane is
acceptable) and as far aft as possible. Refer to AC 43.13
The following factors must also be considered:
Antenna must be mounted as far away as possible from other Very High Frequency
(VHF) antennas.
The antenna should be as close as possible to the transmitter.
Must not foul other antennas in flight.
Antennas should be vertically polarized when aircraft is in the normal flight attitude.
The antenna should be mounted as close to the ELT as practicable. Coaxial cable
connecting the Antenna to the ELT should not cross aircraft production breaks. The
coaxial cable should be secured to the aircraft structure and when the coaxial cable is
installed and the connectors are mated, each end should have some slack.
6.5.1 ROD/GPS Antenna ANNT:XVG:SH:A:XX
This ROD/GPS antenna is compatible with all SkyHunter406 ELT installation kits. The antenna
transmits on the 121.5 MHz and 406.037 MHz frequencies and allows GPS position acquisition
and update the aircraft current position.
6.5.1.1 Antenna Mounting
Using the mounting diagram in section 10 cut out the mounting hole in the aircraft skin. Drill
the mounting holes. Mount the antenna using a doubler plate as required. Use eight screws to
hold the antenna securely in place.
6.5.2 Whip Antenna (121.5 MHz/406 MHz) ANNT:XXW:SH:A:XX
You will notice in the mounting diagram for this Whip antenna located in section 10 that this is
most similar to the original whip antenna mounting. Although you will not have GPS reception
capabilities with this antenna (when ELT is installed) you will only have one hole to drill for
mounting or reuse the existing whip antenna hole.
6.5.3 Right angle antenna and gps connectors
These right angle connectors are available to help with the installation of antennas that are
installed in a restricted space environment.
