INSTALLATION
2.1
INTRODUCTION
This section provides the necessary information for the installing the GTX
327 Transponder, and where
required, optional accessories. Installation of the GTX 327 will differ according to equipment location and
other factors. Cabling will be fabricated by the installing agency to fit these various requirements. This
section contains interconnect diagrams, mounting dimensions, and information pertaining to installation.
Any deviations from the installation instructions prescribed in this document shall be accomplished in
accordance with the requirements set forth in FAA AC 43.13-2A.

UNPACKING AND INSPECTING EQUIPMENT
Carefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurred
during shipment. If the unit is damaged, notify the carrier and file a claim. To justify a claim, save the
original shipping container and all packing materials. Do not return the unit to GARMIN until the carrier has
authorized the claim.

Retain the original shipping containers for storage. If the original containers are not available, a separate
cardboard container should be prepared that is large enough to accommodate sufficient packing material to
prevent movement.

ANTENNA INSTALLATION
2.3.1 Location Considerations
A.
The antenna (GARMIN P/N 010-10160-00) should be well removed from any major
protrusions, such as engine(s), propeller(s), and antenna masts. It should also be as far as
practical from landing gear doors, access doors, or other openings that could effect its
radiation pattern.

practical from landing gear doors, access doors, or other openings that could effect its
radiation pattern.
B.
The antenna should be mounted on the underside of the aircraft and in a vertical position
when the aircraft is in level flight.

C.
Avoid mounting the antenna within three feet of the ADF sense antenna or any other
communication antenna and six feet from the DME antenna.

D.
To prevent RF interference, the antenna must be physically mounted a minimum distance of
three feet from the GTX 327.
three feet from the GTX 327.
NOTE
If the antenna is being installed on a composite aircraft, ground planes must sometimes be
added. Conductive wire mesh, radials, or thin aluminum sheets embedded in the composite
material provide the proper ground plane allowing the antenna pattern (gain) to be maximized
for optimum transponder performance.
