A. Selection
(1) Use only antennas approved for use with the ME406P 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 call Artex Technical Support.
WARNING:Per FAA AC 43.13-2: “Painting an antenna or applying 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 not authorize operators or outside
