A. Selection
1) Use only antennas approved for use with the G406-4 ELT. The ELT will not work properly without
being connected to an antenna for which it was designed.
2) Verify the antenna selected matches the requirements of the specific installation. Considerations
include aircraft maximum rated speed, location restrictions, and any other considerations specific to
the installation.
NOTE: If the combination of a 121.5/243.0 MHz whip antenna and a 406 MHz whip antenna
is selected for installation, the requirements herein apply to both antennas.
SUBTASK 25-62-21-450-001
B. Location
1) Select a suitable location for the antenna.
a) Place the antenna in a location where the antenna can be installed within 15° of vertical and with
at least 30 inches (762 mm) of clearance from other antennas, particularly VHF, in accordance
with RTCA/DO-204, § 3.1.10.2.
NOTE: AC 43.13-2, Chapter 3 recommends a minimum distance of 36 inches (914 mm)
clearance between antennas.
b) Additional location guidance may be found in AC 43.13-2, Chapter 3, which deals specifically with
antenna installations.

C. Installation
NOTE: Refer to the airframe manufacturer’s written instructions and AC 43.13-2, Chapter 3
for antenna installation practices and requirements.
1) Install a doubler plate if necessary to meet rigidity requirements. A 20 lb (9.1 kg) force applied to the
antenna in all directions should not cause an appreciable distortion in the aircraft skin.
2) Install a ground plane if necessary. In certain applications, particularly those where antennas are
installed on composite, fabric, or wood airframes, a ground plane is required.
3) Drill the antenna mounting holes and coax connector holes referring to the appropriate antenna
illustration for hole patterns and hole sizes.
a) See Figure 14 Whip Antennas 110-324 and 110-329 Outlines and Dimensions on page 48 and
Figure 15 Rod Antenna 110-320 Outline and Dimensions on page 48.
4) Mount the antenna referring to the appropriate antenna illustration for hardware requirements,
torque, and other applicable installation requirements.
5) Two coax cables, 6 feet (1.8 m) long, are provided as part of the ELT kit. The 121.5/243.0 MHz cable
has BNC connectors and the 406 MHz cable has TNC (antenna) and TPS (ELT) connectors.
