A. Selection
(1) Use only antennas approved for use with the ME406 Series 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.
(3) Per FAA TSO C126 and ETSO C126, ELTs must be installed with only the components that have
been certified by either the manufacturer of the unit or via a Type Certificate authorization
done by the airframe manufacturer. Contact Artex Technical Support for further information
regarding component and accessory selection.

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: Per FAA TSO C126a, “Those installing this article, on or in a specific type or class of
aircraft, must determine that the aircraft installation conditions are within the TSO
standards. TSO articles must have separate approval for installation in an aircraft.”
CAUTION:Artex cannot verify appropriate antenna selection per each airframe. Many
considerations must be evaluated during the antenna selection process, such as
dynamic / static loading. Certain special considerations need to be accounted for
such as airflow speed over the antenna surfaces (Frontload / Sideload). Consult FAA
AC 43.13-2 and airframe manufacturer for antenna installation practices and
requirements. For more information contact Artex Technical Support.
WARNING:Per FAA AC 43.13-2: "Painting an antenna or apply protective coatings or devices
that are not approved are not allowed [under this AC]. Paint is an RF de-tuner. If an
antenna is painted in the field, paint type and paint thickness present uncontrolled
variables that will affect an antenna's performance and may result in the antenna no
longer meeting its specifications or Technical Standard Order (TSO)." Artex does
