7. Seal the interfaces.
NOTE: The aft cover interfaces do not require sealing.
8. Test the satellite communication equipment as specified by the
manufacturer.
Honeywell recommends towing the aircraft in a figure eight pattern or 360
degrees while monitoring the signal strength.
K. AMT-3800 HGA
(1) Designing an Antenna Interface Adapter
Most installations require the fabrication of an antenna interface adapter to
adapt the flat base of the AMT-3800 HGA to the curved surface of the fuselage.
The AMT-3800 HGA has two weeping/venting locations on the underside of the
unit that must not be blocked. The mounting adapter must provide features to
allow the AMT-3800 HGA to properly vent (for pressure equalization) and weep
condensate. Refer to Figure 3-7 on page 3-13 for the location of these features.
The mounting adapter should not permit water/condensate to become
entrapped. Ensure sufficient drainage to avoid damage and corrosion.
Honeywell can provide installation kits for common airframes—contact
Honeywell for more information.
(2) Selecting a Location for the AMT-3800 HGA
For clear satellite communication, install the AMT-3800 HGA on the top of the
fuselage.
Select a location for the AMT-3800 HGA assembly that minimizes shadowing
from any part of the aircraft structure. The aircraft tail (on fixed wing platforms)
may cause a small amount of blockage. You can minimize this blockage by
installing the AMT-3800 HGA forward on the fuselage so that it has a clear view
in any direction from 5° to 90° in elevation and 360° in azimuth.
