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.

Location
1)
Select a suitable location for the antenna.

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.

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. CONTACT ARTEX
TECHNICAL SUPPORT FOR MORE INFORMATION.
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 NOT
AUTHORIZE OPERATORS OR OUTSIDE MAINTENANCE ORGANIZATIONS TO
PERFORM FIELD REPAIRS OR PAINTING.
