The 1.8 Meter Transmit-Receive Antenna System is designed for two-way satellite communications, and is suitable for commer-
cial or consumer use.
TOOLS REQUIRED:
Compass
Clinometer
228 mm or 9 in Magnetic Bubble Level
Torque Wrench (Capacity 5 - 237 N-m) (4 - 175 ft-lb)
30 mm ( 1.25 in) Adjustable Crescent Wrench
24 mm or 15/16 in Deep Socket (1/2 in or 13 mm Drive)
ADDITIONAL INSTALLATION MATERIALS (Not Included with Antenna)
Grounding Rod, Clamp & Grounding Block - As required by National Electric Code or local codes.
Ground Wire - #10 solid copper or #8 aluminum as required by National Electric Code or local codes (length required).
RG-6 Coaxial Cables from antenna to indoor unit(s).
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.
SITE SELECTION
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 Wind loads" in the Appendix
"B" on page 11.
