SECTION I INTRODUCTION
1.0 GENERAL INFORMATION
This manual describes the assembly and installation of CPI’s 1.2 meter antenna
system. The CPI 1.2 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. The CPI 1.2 meter has an f/d ratio of .8
and an offset angle of 17.30°.
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 onmatters 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 CPI’s Customer Service Department at:

STEP 1.
Hi - Lo Screw
The Az/El Positioner Assembly is supplied with
a Mast Sleeve for use on 2.88” OD mast
pipes.
If the install is on a 2.88” OD mast pipe, the
Mast Sleeve should be inserted into the
Canister before proceeding to reduce the
Canister’s inside diameter appropriately.
If the install is on a 3.00” OD (76mm OD) mast
pipe, the Mast Sleeve can be omitted and
discarded.

2.2 FEED SUPPORT ASSEMBLY
NOTE: These instructions are intended as a general reference for feed
support assembly. If your antenna system has specific feed support
installation instructions, then refer to them at this time.
CAUTION: During the assembly procedure, the sequence of instructions
must be followed. DO NOT TIGHTEN ANY HARDWARE UNTIL
INSTRUCTED. Refer to the feed support parts list and steps.

SECTION III ANTENNA POINTING
3.0 ANTENNA POINTING
The 1.2 meter reflector contains a 17.3° elevation offset look angle. Therefore,
when the reflector aperture is perpendicular to the ground, the antenna is actually
looking 17.3° 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 CPI’s Technical Support Department for
additional recommendations.
STEP 1: BEFORE ADJUSTING ELEVATION LOOSEN THE HARDWARE ON
BOTH SIDES OF THE POSITIONER, REFER TO FIGURE 2 FOR
LOCATION. 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 side of
the positioner. This scale is used for nominal readings and is accurate to
±2 degrees. Note: Elevation rod is for adjustment only, it is not
intended to be part of the structural integrity of the assembly,
tightening the elevation rod is not necessary. Snug the hardware at the
side of the positioner.
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 the nut under the azimuth pivot then
turn the single hex bolt at the back of the positioner in either direction. Note:
Azimuth rod is for adjustment only, it is not intended to be part of the
structural integrity of the assembly, tightening the azimuth rod is not
necessary.
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
CPI’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 CPI 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 galvanized 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.
