SECTION I GENERAL INFORMATION
1.0 INTRODUCTION
This manual describes the assembly and installation of CPI’s 1.8M Rx/Tx offset
antenna system with an Az/El mount (series number 1194). The CPI 1.8M is a
rugged, reliable antenna system, which will operate in the 10.95 to 12.75 and 14.0
to 14.5 GHz frequency bands for Ku-Band systems with high efficiency and at the
same time successfully withstand the effects of the environment.
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. 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 damageclaims.
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:

SECTION III ANTENNA POINTING
3.0 ANTENNA POINTING
The 1.8meter reflector contains an elevation offset look angle. Therefore, when
the reflector apertureis perpendicular to the ground, the antenna isactually looking
17.3° in elevation. Refer to Figure 2.
Step 1: Place an inclinometer on the reflector support tube as shown in Figure 2.
The surface allows for the offset look angle and therefore a direct reading
can be taken for elevation.
Step 2: Adjust the reflector up or down in elevation by turning the two 3/4" hex nuts
at the elevation block until the desired elevation is read on the inclinometer.
Snug the hardware.
Step 3: Azimuth Adjustment: With the electronics set to acquire the satellite, rotate
the antenna in azimuth until the satellite is found. Snug the azimuth
adjustment hardware.
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.
