INSTALLATION
2.1
INTRODUCTION
This section provides the necessary information for installing the GTX 330 Mode S Transponder, and where
required, optional accessories. Installation of the GTX 330 will differ according to equipment location and other
factors. Cabling will be fabricated by the installing agency to fit these various requirements. Appendix B contains
interconnect wiring diagrams, mounting dimensions, and information pertaining to installation. Each installation
shall be accomplished to meet the requirements of FAA AC 43.13-2A.
2.2
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 mounted away from 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.
B. The antenna should be mounted on the underside of the aircraft and in a vertical position when the
aircraft is in level flight. The diversity antenna should be mounted on the top of the aircraft.
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 330.
