2.3.2 Antenna Location Considerations

Antenna mounting should utilize the aircraft manufacturer's Type Certificated antenna location and style

of antenna. The antenna installation should be installed in accordance with AC 43.12-2A Chapter 3.

Note that penetration of the pressure vessel on the pressurized aircraft requires additional data not

contained in this manual (see Section 2.5).

A. The antenna (Garmin P/N 010-10160-00) or equivalent 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 affect the

radiation pattern.

B. The main antenna should be mounted vertically on the bottom 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 32.

If the antenna is being installed on a composite aircraft, sufficient ground plane

material must 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.
