7. Installation of Antennas
The antenna should be mounted on the bottom of the aircraft if possible.
Unpainted aluminum base must make good electrical contact with airframe. Antenna should be
installed on flat surface.
A bead of sealant such as Dow Corning RTV-738 should be applied to the outside perimeter of
the mounting surface.
See Figures 3-5 through 3-15 for appropriate antenna mounting dimensions.
A. AT-560 and AT-5000
See the AT-560 and AT-5000 envelope drawings, Figures 3-5 and 3-7, for dimensions.
Mount antenna with No. 10 screws.
B. FC-5000
Note: The FC-5000 Logic Converter is required for the AT-560 and AT-5000 antennas.
See the FC-5000 envelope drawing, Figure 3-15, for dimensions.
C. AT-160 and AT-150
See the AT-160 and AT-150 envelope drawings, Figures 3-6 and 3-9, for dimensions.

If antenna is installed on top of aircraft, drainage holes at smaller end of antenna should be
plugged with blanking plugs and RTV. Drainage holes in antenna base flange at mounting
face should not be obstructed.
If antenna is installed on underside of aircraft, drainage holes at smaller end of antenna base
flange at mounting face should be sealed with a small fillet of RTV.
