INTRODUCTION: How to Use This Manual
I.I Purpose & Overview
PURPOSE
The scope of this manual is intended to provide station personnel with the base installation, operation, and
maintenance requirements necessary for a 9.3-Meter C -Band Earth Station Antenna (9.3m ESA). This manual
provides a convenient reference for authorized operator/service personnel requiring technical information on
general system or specific subsystem equipment.
NOTE: All antenna option instructions are included in the individual kit shipped with that part.
Top Level Assembly Number is as follows:
ES93-1: 9.3m ESA C-Band. Motorizable Mount with Az & El Jackscrews

OVERVIEW
The installation, operation, and maintenance of the 9.3m ESA require qualified and experienced personnel.
ASC Signal installation, operation, and maintenance instructions are illustrated for such personnel.
Additionally, the antenna should be inspected by qualified personnel to verify proper installation, maintenance,
and condition of equipment as described in Preventive Maintenance. The basic equipment and accessories are
either manufactured or design controlled by ASC Signal Corporation.
The prerequisite information necessary for the 9.3m ESA can be found in this section. Furthermore, this
section should be reviewed before performing the installation, operation, or maintenance. Warnings,
recommended tools, and the antenna parts can be verified and/or determined with such a review.
I.II Description
The 9.3m ESA provides high gain and exceptional pattern characteristics. The electrical performance and
exceptional versatility provides the ability to configure the antenna with your choice of linearly- or circularly-
polarized 2-port or 4-port combining network. That versatility is provided at the time of initial purchase, as well
as in the future, as your satellite communication requirements evolve.
The aluminum reflector is precision formed for accuracy and strength, requiring minimal assembly. The
reflector assembly is 30-feet (9.3-meters) in diameter and segmented in a twenty piece configuration to reduce
shipping volume and facilitate transport to remote sites. Reflector panels are chromate converted and painted
with a highly reflective white paint.
The versatile tripod mount can be purchased with motorizable capabilities. The tripod mount features 180°
Azimuth coverage in three continuous 120° overlapping ranges and executes 90° continuous Elevation
adjustment. This large adjustment range provides non-critical foundation orientation and the ability to view
geostationary satellites from horizon-to-horizon, from any location worldwide.
The motorizable tripod mount features self-aligning bearings for the elevation pivots, resulting in "zero"
backlash. This mount has the ability to be upgraded for High-Speed motorized operation, including step-
tracking or SmarTrack
®
applications. The motorizable mount type is indicated by the ES93 or ES93HS letters
within the antenna type number. The addition of the letters "HS" within the antenna type number indicates that
the mount includes High-Speed Az/El machine jackscrews, instead of corresponding Azimuth/Elevation strut
assemblies. The Az/El jackscrews are equipped for integration with the optional motor drive systems. A cross-
axis grounding kit is supplied with each mount to ensure electrical interconnectivity of the complete structure.
The aluminum enclosure and hot-dipped galvanized steel mount maintain pointing accuracy and ensure
durability and reliability. The antenna and standard manual mount with enclosure will survive 125 mph (200
km/h) wind, in any position of operation, without damage or permanent deformation in moderate
coastal/industrial areas. Severe conditions require additional protection.
