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

1.6 SUGGESTED MAST & FOUNDATION
FIGURE 1.
NOTES:
1. 2 x 2 x 1/4 HRS Angle and schedule 40 pipe should conform with ASTM A36 and ASTM A53
Type E and S Grade B.
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.
8. Foundation meets the design requirements as set forth by the uniform building code.
(1982 edition)
(CPI DOES NOT REPRESENT OR WARRANT THAT ANY PARTICULAR DESIGN OR SIZE OF
FOUNDATION IS APPROPRIATE FOR ANY LOCALITY OR EARTH STATION INSTALLATION.
