Total azimuth coverage for the Model 8009AE (180°) mount is 180°

continuous. The elevation axis for both the Model 8009AE 120° and 180°

antenna will cover 0° to 90° in one continuous sector. Elevation travel will not

be limited by reflector de-icing. The 30-ton azimuth actuator and 30-ton

elevation actuator will allow the antenna to survive 201 km/h [125 mi/h] at

any antenna orientation.

All manual drive actuators can be operated manually or with an auxiliary

power source such as a drill motor. All motorized actuators may also be

operated manually if required.

Grounding cables are provided to ensure system electrical grounding

between the antenna reflector and the antenna mount structure. Tapped

holes are provided in the mount base plates for attachment to a suitable

foundation grounding system.

Included as optional equipment on the mount are a ladder and work

platform assembly. These components provide safe and convenient access to

the feed electronics inside the antenna hub and to the elevation drive motor

for servicing and inspection. The ladder and platform are designed to be fully

compatible with OSHA specifications.

Each antenna foundation is an essential part of the antenna installation. The

foundation should be oriented so that the desired pointing angles can be

achieved and accurately maintained under maximum wind loads.

NOTE

The Model 8009A (120°), Model 8009AE (120°) and Model

8009AE (180°) require different foundation specifications. See

the appropriate foundation installation kit for the special

features required for each antenna option.

It is imperative that competent engineering assistance be engaged to assure

that the foundation is properly designed for the local site conditions and

building codes. The contractor does not imply or warrant that the foundation

design shown as typical on drawings in this manual, or other ViaSat

documents, is appropriate for any particular locality or site condition. The

structural steel mounts have been designed in accordance with the American

Institute of Steel Construction (AISC) specifications for Design, Fabrication,

and Erection of Structural Steel Buildings as presented in the Manual of Steel
