SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
(2) Installing the Blade Antenna
I.
AMT-1800 IGA
The AMT-1800 IGA is provisioned by variant selection to provide conformal
mating with a select list of airframe crown radii. Installations on airframes other
than those identified in the product variant list will require a custom antenna
interface mounting adapter which adapts the curved fuselage to the flat base of
the AMT-1800 IGA.
Design of the mounting adapter should not permit water/condensate to become
To simplify installation of the AMT-1800 IGA on common aircraft, Installation Kits
are available from Honeywell. These kits include, most significantly, an AIM
Adapter that meets the requirements described in this section. Contact Honeywell
for information on availability of the AIM adapter for a given airframe.entrapped.
Ensure sufficient drainage to avoid damage and corrosion.
(1) Antenna to Aircraft Fuselage
The AMT-1800 IGA will be installed using the custom gasket provided with the
system, and quantity two NAS1611-031 O-rings (not provided), to seal the faying
interface between the underside of the antenna and mounting surface to provide a
pressure seal and to avoid water entrapment and corrosion. Clean the faying
surfaces of the AMT-1800 IGA and the fuselage using approved avionics
solvents.(such as IPA) prior to installation of the gasket.

Separation resulting in greater than 40dB of isolation should be provided
between the Blade Antenna and the GPS Antenna at 1572.0 to 1616.0 MHz
(GPS band) and 1626.5 to 1660.5 MHz (SATCOM band). The Blade
Antenna provides 50dB of filtering. If another antenna is installed, check
the documentation for GPS isolation.
To install the antenna assembly:
1. Carefully position and secure the antenna assembly on the fuselage, taking
care not to damage exposed cabling.
2. Connect all cables to the antenna assembly.
Install the Blade LGA so that the maximum RF cable loss is 0.3 dB.
NOTE: The cable loss limit of 0.3 dB is a generic value that covers all aircraft
types and equipment configurations. Depending on specific installation
environments, the cable loss may be increased without compromising
system performance or invalidating system certification. If required,
contact Honeywell for more information.
For information about installing the Blade LGA, refer to Figure 3-5 on page 3-9.
