3. Antenna Installation
The external antenna can be either of whip, rod or blade type according to
aircraft speed. Use only approved antennas.
Connection to the ELT will be carried out with a 50 Ohm coaxial cable (RG58
for example) ended with two male BNC connectors.
A. Antenna Installation Recommendations
(1) FAA Recommendations
Installation must be made by qualified personnel in accordance with FAA
regulations. Duplicating a previous installation may not be acceptable. Methods
for installing antenna are outlined in AC43.13-12, refer to:
FAA - Advisory Circular 43.13-2A (Acceptable Methods, Techniques, and
Practices - Aircraft Alterations), specifically, Chapters 1, 3, 11 and 13.
(2) RTCA DO-204 Requirements for ELT location
"ELT antennas should be located away from other antennas to avoid disruption
of antenna radiation patterns."
"Idealistically, for the 121.5 MHz ELT antenna, 2.5 meter separation is sufficient
separation from VHF communications and navigation receiving antennas to
minimize unwanted interferences."
"ELT antennas should be vertically polarized when the aircraft is in the normal
flight attitude."
"ELT antenna mounting surface should be able to whistand a static load equal
to 100 times the antenna weight applied at the antenna mounting base in all
directions."
"The antenna should be mounted as close to the respective ELT as applicable.
