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.
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.
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.
