SECTION I GENERAL INFORMATION
1.0 INTRODUCTION
This manual describes the assembly and installation of CPI’s 1.8M antenna system with Az/El mount. The
CPI 1.8M is a rugged, reliable antenna system, which will operate with high efficiency and at the same time
successfully withstand the effects of the environment. The basic 1.8M antenna consists of an offset reflector,
reflector support, feed support structure and Az/El positioner.
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 antenna containers should be unpacked and inspected at the earliest date to ensure that all material has
been received and is in good condition.
1.2 FRIEGHT 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 is not due to the freight carrier should be directed
to CPI’s Customer Service Department at:

1.6 SITE SELECTION
In order to achieve maximum performance of your antenna system, it is important to select the correct
location for the antenna. The following guidelines should be observed when selecting a site for the instal-
lation.
1. The line of site to the satellite should be clear of any obstructions, such as trees or buildings.
2. The site should be relatively flat and level for ease of installation and access to the antenna.
3. The site should be checked for underground obstruction, such as buried cables or pipes.
4. All local building codes should be adhered to (i.e. grounding, foundation requirements, zoning
rules, setbacks, etc.).

4096-668
CPI Satcom & Antenna Technologies 1.8M Ka-BAND Rx/Tx ANTENNA
1.7 SUGGESTED MAST & FOUNDATION
The required interface from the foundation to the mount is 5” schedule 80 pipe
(5.56”O.D.). A suggested in-ground foundation is shown in Figure 1.
FIGURE 1.
NOTES:
1. 2 x 2 x 1/4 HRS Angle and schedule 80 pipe should conform with ASTM A36 structural steel.
2. All concrete should conform to building code standards and have a minimum compressive strength of 3000
PSI at 28 days. (Per ACI-318-77)
3. Soil bearing capacity should be no less than 2000 PSF.
4. Concrete should be poured against undisturbed soil.
5. Allow concrete 24 hours set time before installation of antenna.
6. The antenna should be properly grounded to meet applicable local codes.
7. Minimum depth as shown or extend to local frost line.
(CPI DOES NOT REPRESENT OR WARRANT THAT ANY PARTICULAR DESIGN OR SIZE OF
FOUNDATION IS APPROPRIATE FOR ANY LOCALITY OR EARTH STATION INSTALLATION.)

2.0 ANTENNA ASSEMBLY
Follow the steps below in the order shown to assemble the antenna. Because of the weight and
size of some of the antenna components, a minimum two person crew is recommended. Do not
tighten any hardware until instructed to do so.
Installing the AZ/EL assembly onto the mast pipe
1. Use a ½-inch open-end wrench to loosen the eight canister set screws until they are flush with
the inside wall of the canister.
2. Lift the AZ/EL assembly (Item #3) and slide the canister over the top of the mast pipe.
3. Rotate the AZ/EL assembly until the reflector side is oriented in the general direction of the
satellite as shown.
4. Snug the eight canister set screws enough to prevent the assembly from rotating. Do not
tighten until instructed to do so later in the assembly.

SECTION IV ANTENNA POINTING
4.0 Alignment To Satellite
CPI’s 1.8 meter Az/El mount requires that the antenna be aligned to the satellite orbital arc
initially by a trained installer.
4.1 Initial Alignment
The 1.8 meter offset reflector contains a 17.35oelevation offset look angle. Therefore,
when the reflector aperture is perpendicular to the ground, the antenna is actually looking
17.35° in elevation.
1) Aligning to satellite: Attach an inclinometer to the reflector support structure as
shown in figure 4.1. Add 17.35° to the reading on the inclinometer to accommodate
the reflector’s offset angle.
2) Raise or lower the antenna to find the desired elevation by turning the 3/4" nuts
located at the elevation block. Position the top nut so that it will not interfere with
adjustment. Turn the bottom nut clockwise to increase elevation and counter
clockwise to decrease elevation.
3) After the correct elevation angle is set, rotate the antenna in azimuth by loosening
the canister and turning the entire assembly on the mast pipe. Rotate azimuth until
a signal is reached.
4.2 Fine Tuning
Peak the antenna signal by fine adjustments made in both azimuth and elevation.
Securely tighten the eight canister set screws.
Use the bottom hex nut of the elevation adjustment rod to slowly raise and lower the antenna until
maximum signal is achieved.
Next, use the azimuth adjustment rod hex nuts to adjust left and right until maximum signal is
achieved.
Repeat steps #2 and #3 until maximum signal is achieved.
Securely tighten all hardware used for adjustment.

SECTION V MAINTENANCE
5.0 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. The materials used in the construction of this Earth Station Antenna
virtually eliminate any maintenance repairs.
5.1 Periodic Inspection
It is suggested that a periodic inspection be performed at least every six months.
NOTE: After any very severe weather conditions, inspection of the antenna should be
performed to determine if foreign objects have caused damage or if survival specifications
have been exceeded.
This inspection should include the following:
1) Check all bolting locations - all bolts should be tight.
2) Check all structural members - repair or replace if damaged.
3) Check the foundation anchor bolts - they must be secure and with no failure signs
in foundation.
4) Check for corrosion - on the reflector structure and mount.
5.2 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 other
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.
