1.3 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 installation.
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.).
1.4 FOUNDATION REQUIREMENTS

Prodelin's recommended foundation for the antenna system is shown in figure 1.
however, each installation must be tailored to the specific requirements of the
site. It may be necessary to contact a local engineer or building department for
foundation design or approval at any particular site.
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.
PRODELIN CORPORATION DOES NOT REPRESENT OR WARRANT THAT ANY PARTICULAR DESIGN
OR SIZE OF FOUNDATION IS APPROPRIATE FOR ANY LOCALITY OR EARTH STATION INSTALLATION
