4) Mount the antenna using four 100º countersink #8-32 (M5) stainless steel machine
screws and associated hardware. Tighten to 20 inch-lbs (226 Newton-cm) max.
5) Apply a small, smooth fillet with RTV sealant around the periphery of the antenna
base to seal out moisture.
6) Install the antenna cable. Artex suggests using the standard 6-foot (1.8M) antenna
cable (supplied with most kits).

2.5 Mount Remote Switch
TSO C126 requires the installation of a remote switch. This switch is NOT optional. The specific
requirement is found in RTCA/DO-204, Section 2.2.6.
The Artex standard remote switch is designed so that if its wires are cut or shorted together the
emergency operation of the ELT is unhampered although the ELT may activate and not “reset”
if the wires are shorted together.
Select a switch mounting location that is easily seen and reached by the pilot and out of direct
sunlight. The Artex remote switch requires approximately 1.3” X 2.0” (33 X 50.8 mm) of panel
area to mount. A space is also required for a warning placard, measuring 2.25” X 0.25” (57 X
6.5 mm), which should be placed close to the installed switch. Approximately 3 inches (75mm)
of clearance behind the panel is required for the switch assembly, mating connector and
harness.
Mark and remove the rectangular cutout for the remote switch assembly. Dimensions are
shown in the Specifications. Fit the switch assembly into the cutout and mark the four
mounting screw hole locations. Drill mounting screw holes with #31 (0.120”) (3.0 mm) drill.
Mount using the 4-40 X ½” Phillips pan head screws, lock washers and nuts provided.
After switch is installed, apply “For Aviation Emergency Use Only / Unauthorized Use Prohibited”
placard (supplied in kit) as close to the switch as practical.
