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 while
monitoring the signal strength.
Position the AMT-700 HGA Assembly so that it can be pointed in any direction
from 5° to 90° in elevation, and 360° in azimuth, and not be subject to shadowing
from any part of the aircraft structure. Make sure that the area around the
Antenna Assembly is free of any objects, which might interfere with the
antenna's moving mechanical parts and coaxial cable.
Orientation of the AMT-700 HGA is defined with respect to the principal axes
of the antenna. The principal axes are illustrated in Figure 3-8 on page 3-15.
The connector access cover on the radome is towards the aft of the aircraft. In
this orientation, the principal axes of the AMT-700 HGA should be aligned with
those of the aircraft to within ± 0.25°. This is the default position for the AMT-700
HGA.
You can install the AMT-700 HGA in a position that is slightly offset from the
default position. The HDU can be configured to compensate for installation
offsets, the procedure for configuring the HDU is provided in the System Setup
Section 1F. This is the preferred method for applying any antenna installation
offsets. Optionally, software in the AMT-700 can accommodate an offset to
correct beam steering. During the initial installation, set the pitch, roll, and
rotation offset angles to within ± 0.25° in the AMT-700 HGA EEPROM—
MN-1428-10010 provides information about setting up the AMT-700 HGA.
To install the AMT-700 HGA:
1. Select the location for mounting the Antenna Assembly.
2. Secure the Antenna Assembly.
The AMT-700 HGA attaches to either four (4) side mounts OR four (4)
bottom mounts (both not required) on the aircraft/interface mount in four
(4) locations.
NOTE: Do not make power connections at this time.
