SECTION I INTRODUCTION

1.0 GENERAL INFORMATION

This manual describes the assembly and installation of Prodelin's 1.2 meterantenna system. The Prodelin 1.2 meter is a rugged and reliable mount whichwill operate in the Ku-Band frequency with high efficiency and at the same timesuccessfully withstand the effects of the environment.

These instructions are listed by sections that cover all areas of assembly andinstallation. Additional sections are included in the manual to provide informationon antenna alignment to the satellite and maintenance.

1.1 UNPACKING AND INSPECTION

The system containers should be unpacked and inspected at the earliest date toinsure that all material has been received and is in good condition. A completepacking list for each major component is supplied.

1.2 FREIGHT DAMAGE

Any damage to materials while in transit should be immediately directed to thefreight carrier. He will instruct you on matters regarding any freight damageclaims.

1.3 MATERIAL - MISSING OR DAMAGED

Any questions regarding missing or damaged materials that is not due to thefreight carrier should be directed to Prodelin's Customer Service Department at:

1.5 SITE SELECTION

In order to achieve maximum performance of your antenna system, it is importantto select the correct location for the antenna. The following guidelines should beobserved when selecting a site for the installation.

1. The line of site to the satellite should be clear of any obstructions, such astrees or buildings.

2. The site should be relatively flat and level for ease of installation andaccess to the antenna.

3. The site should be checked for underground obstruction, such as buriedcables or pipes.

4. All local building codes should be adhered to (i.e. grounding, foundationrequirements, zoning rules, setbacks, etc.).


1.6 FOUNDATION INTERFACEThe required interface from the foundation to the mount is 2-1/2" schedule 40pipe (2.88" O.D.). A suggested in-ground foundation is shown in Figure 1.

4.0 INITIAL POINTING

The 1.2 meter reflector contains a 22.6° elevation offset look angle. Therefore,when the reflector aperture is perpendicular to the ground, the antenna is actuallylooking 22.6° in elevation. Refer to Figure 2.

Step 1: Place an inclinometer on the reflector support angle as shown in Figure 2.

Step 2: Adjust the reflector up or down in elevation by turning the two ½" hex nutsat the elevation channel until the desired elevation is read on the(inclinometer reading plus 22.6° = elevation angle). Note: Be sure that theelevation pivot hardware (3 places) is loose enough to allow adjustmentwithout damaging (bending) the elevation rod. Snug the hardware.

Step 3: Azimuth Adjustment: Loosen the six set screws on the canister. With theelectronics set to acquire the satellite, rotate the antenna in azimuth untilthe satellite is found. Snug the six set screws.

Step 4: Peak the antenna signal by fine adjustments made in both azimuth andelevation until the optimum signal is achieved.

Step 5: Tighten all hardware used for adjustment.

SECTION V MAINTENANCE

5.0 MAINTENANCE OVERVIEW

After installation, the antenna requires only periodic inspection. It is anticipatedthat maintenance, if required, will be minimal and easily handled by a local or in-house maintenance staff.

5.1 REFLECTOR

Prodelin's reflector does not require any maintenance. The compositeconstruction of the reflector is virtually impervious to any damages that could becaused by weather or atmospheric conditions.

It is only necessary to inspect for any physical damage done by vandalism orvery severe weather conditions.

Should any damage be detected to a portion of the reflector, contact theCustomer Service Department at Prodelin for recommendations involvingreflector repair.

5.2 MOUNT AND REFLECTOR SUPPORT STRUCTURE

The mount and reflector support structure supplied with this antenna is of steelconstruction and has a galvanized finish.

If there are any signs of structural failure, the mount members that are damagedshould be repaired or replaced.

CORROSION: Any corrosion on steel members may be repaired with a cold,zinc-rich galvanizing paint.

5.3 FEED AND FEED SUPPORT

The feed support and feed rods should be inspected to insure that all hardware issecure. The feed/radio mounting bolts should be tight.

The feed horn window should be inspected to insure that it is intact so that nomoisture can collect inside the feed horn.
