PREINSTALLATION MATERIALS CHECKLIST

Grounding Rod Clamp & Grounding Block - As Required by National Electric Code or local codes.

Ground Wire - As Required by National Electric Code or local codes (length required).

Coaxial Cable - Size and length required.

Concrete: See “Ground Pole” section for quantity.

M10 or #3 Rebar: See “Ground Pole” section for quantity. Deformed steel per ASTM A615, Grade 40 or 60.

The first and most important consideration when
choosing a prospective antenna site is whether or not the
area can provide an acceptable “look angle” at the
satellites. A site with a clear, unobstructed view is
preferred. Also consider obstruction that may occur in the
future such as the growth of trees. Your antenna site must
be selected in advance so that you will be able to receive
the strongest signal available. To avoid obstructions, etc.,
conduct an on-site survey with a portable antenna.

As with any other type of construction, a local building
permit may be required before installing an antenna. It is
the property owner’s responsibility to obtain any and all
permits.

Before any digging is done, information regarding the
possibility of underground telephone lines, power lines,
storm drains, etc., in the excavation area should be
obtained from the appropriate agency.

Because soils vary widely in composition and load capacity,
consult a local professional engineer to determine the
appropriate foundation design and installation procedure.
A suggested foundation design with conditions noted is
included in this manual for reference purposes only (see
page 4). To assist in the foundation design, refer to
“Antenna Windloads” in the Appendix “B” on page 15.
