General Information
1.1 Introduction
This manual contains information needed to properly install, operate, and
maintain ViaSat's 11-Meter (11M) Earth Station Antenna. The antenna is
eleven meters in diameter. It provides high quality receive/transmit and
receive-only capabilities for both domestic and international C-band or Ku-
band applications. The antenna consists of an 11M-shaped reflector, a
shaped subreflector, and a linearly or circularly polarized feed on a high-
strength structural steel elevation-over-azimuth mount. The mount's stiff,
rugged construction provides the pointing accuracy needed for proper
operation under adverse wind conditions.
This chapter of the manual contains general descriptions and specifications
on the mount, reflector, feed, and subreflector. Chapters 2 through 4 contain
information pertaining to antenna installation, operation, and maintenance.
All warnings and cautions should be reviewed before any procedures are
performed. Failure to do so may result in personal injury or equipment
damage.
ViaSat, Inc. makes every effort to ensure that the information contained
herein is correct and complete.
1.2 Mount Description
The 11M reflector can use either of two mounts, the Model 8020-120 and the
