SECTION I INTRODUCTION
1.0 GENERAL INFORMATION
This manual describes the assembly and installation of Prodelin's .89/.98 meter
antenna systems. The Prodelin .89/.98 meter is a rugged and reliable mount
which will operate in the Ku-Band frequency with high efficiency and at the same
time successfully withstand the effects of the environment. Prodelin’s .89/.98
Meter antennas have an F/D ratio of .8, an offset angle of 16°, and is commonly
used with a 39° Prodelin Feed Horn.
These instructions are listed by sections that cover all areas of assembly and
installation. Additional sections are included in the manual to provide information
on antenna alignment to the satellite and maintenance.
1.1 UNPACKING AND INSPECTION
The system containers should be unpacked and inspected at the earliest date to
insure that all material has been received and is in good condition. A complete
packing list for each major component is supplied.
1.2 FREIGHT DAMAGE
Any damage to materials while in transit should be immediately directed to the
freight carrier. He will instruct you on matters regarding any freight damage
claims.
1.3 MATERIAL – MISSING OR DAMAGED
Any questions regarding missing or damaged materials that are not due to the
freight carrier should be directed to Prodelin's Customer Service Department at:

SECTION III ANTENNA POINTING
3.0 ANTENNA POINTING
The .89/.98 meter reflector contains a 16° elevation offset look angle. Therefore,
when the reflector aperture is perpendicular to the ground, the antenna is actually
looking 16° in elevation. Refer to Figure 2.
Note: The following alignment procedure is intended only as a general reference
guide for this antenna. For proper antenna performance, accurate
alignment is critical. Therefore, it is recommended that your own detailed
procedure be used or contact Prodelin’s Technical Support Department for
additional recommendations.
STEP 1: Adjust the reflector up or down in elevation by turning the 5/16” Bolt at the
az/el positioner until the desired elevation is read on the ‘B side’ of the
positioner. This scale is used for nominal readings and is accurate to ±2
degrees Note: Be sure that the elevation pivot hardware is loose enough
to allow adjustment without damaging (bending) the elevation rod. Snug
the hardware.
STEP 2: Azimuth Adjustment: With the electronics set to acquire the satellite,
rotate the antenna in azimuth until the satellite is found. Tighten the
canister hardware at this time.
STEP 3: Fine azimuth adjustment is achieved by loosening the three hex nuts
inside the Az/el positioner and turning the single hex bolt at the back of the
positioner in either direction.
STEP 4: Peak the antenna signal by fine adjustments made in both azimuth and
elevation until the optimum signal is achieved.
STEP 5: Tighten all hardware used for adjustment.

SECTION IV MAINTENANCE
4.0 MAINTENANCE OVERVIEW
After installation, the antenna requires only periodic inspection. It is
anticipated that maintenance, if required, will be minimal and easily
handled by a local or in-house maintenance staff.
4.1 REFLECTOR
Prodelin's reflector does not require any maintenance. The composite
construction of the reflector is virtually impervious to any damages that could be
caused by weather or atmospheric conditions. It is only necessary to inspect for
any physical damage done by vandalism or very severe weather conditions.
Should any damage be detected to a portion of the reflector, contact the
Customer Service Department at Prodelin for recommendations involving
reflector repair.
4.2 MOUNT AND REFLECTOR SUPPORT STRUCTURE
The mount and reflector support structure supplied with this antenna is of steel
construction and has a powder painted finish.
If there are any signs of structural failure, the mount members that are damaged
should be repaired or replaced.
4.3 FEED AND FEED SUPPORT
The feed support and feed rods should be inspected to insure that all hardware is
secure. The feed/radio mounting bolts should be tight.
The feed horn window should be inspected to insure that it is intact so that no
moisture can collect inside the feed horn.
