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 4.5-Meter Earth Station Antenna (4.5m ESA). This manual provides
a convenient reference for authorized operator/service personnel requiring technical information on general
system or specific subsystem equipment.

OVERVIEW
The installation, operation, and maintenance of the 4.5m ESA require
s
qualified and experienced
personnel.
Kratos
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
Kratos Defense & Security
Solutions, Inc.
.
The prerequisite information necessary for the 4.5m 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 4.5m 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 transmit/receive as well
as receive only, and for either linearly- or circularly-polarized C-Band, linearly-polarized Ku-Band, Hybrid C-/Ku-
Ban, or X-Band operation. Both pedestal and tripod mounts are available (motorization available for pedestal
only). The versatility is provided at the time of initial purchase, as well as in the future, as your satellite
communication requirements evolve.

The segmented aluminum reflector panels are precision formed for accuracy and strength. The 6-piece reflector
panel design ensures that the assembled reflector will maintain the extremely accurate surface contour and
guaranteed performance without the need for reflector realignment.
The versatile Tripod Mount features 164° of coarse Azimuth coverage in four overlapping ranges, and 90° coarse
Elevation adjustment. This large range of adjustment provides the ability to view geostationary satellites from
horizon-to-horizon, from any location within the continental United States. The broad mount leg spacing enables
efficient load transfer to the foundation, providing additional mount rigidity.
The Motorizable Pedestal Mount features self-aligning bearings for the Elevation pivots, resulting in "zero"
backlash. This mount can be operated manually, but has the ability to be upgraded for motorized operation,
including step-tracking or SmarTrack
®
applications. The motorizable mount type is indicated within the antenna
type number as ES45MP or ES45MPJ. The addition of the letter “J” within the antenna type number indicates
that the mount includes Azimuth/Elevation machine jackscrews, instead of corresponding Azimuth and Elevation
strut assemblies. The Azimuth/Elevation jackscrews are equipped for integration with the optional motor drive
