Page 20: Storage And Transportation
3.2 Storage Whenever the HGA-7001 is being stored, it is advised the unit is placed inside its shipping container. The container must be stored in a dry area (< 50% RH) while the temperature must not exceed –55 °C (–67 °F) or +85 °C (+185 °F). - Page 21 HGA-7001 Installation Manual THIS PAGE LEFT BLANK INTENTIONALLY COMPANY CONFIDENTIAL Document: 862-A0089_IM issue 1.6 Page 21 of 45...

Page 24: Mounting
THROUGHOUT THE INSTALLATION PROCESS. 5.2 Mounting Location and General Considerations The HGA-7001 must be mounted on the top of the fuselage with a clear view of the sky. The installation must provide adaptation of the flat underside of the HGA-7001 to the fuselage. - Page 25 Lightning Strike The HGA-7001 is rated for use in Zone 2A – swept strike zone. (Refer to paragraph 2.2). RF Blockage Aircraft surfaces that interrupt the direct line of sight between the antenna and satellite will cause a variable amount of blockage of the antenna RF beam.
-
Page 26: Figure 10: Rf Blockage Caused By Aircraft Wing
Figure 10: RF Blockage Caused By Aircraft Wing Co-location with other Antennas The HGA-7001 conforms to the recommended RTCA/DO-160E Radiated Emission requirements with margin. However, transmission from any Inmarsat-based SATCOM system may still affect the operation of other RF systems in particular cases. -
Page 27: Structural Modifications
Engines and APU Inlets The HGA-7001 must be positioned out of the zone of influence of the engines and APU inlets. This must be verified by the installer. -
Page 28: Mounting/Adaptor Plate
OP-121 REPAINTING HGA-7001 ANTENNA. 5.5 Sealing The HGA-7001 is a breathing design and therefore no special precautions need to be taken for sealing of the antenna itself. The installer must take suitable precautions to prevent water from becoming trapped between the HGA-7001 and the aircraft fuselage, as this may result in corrosion. -
