Antenna installation safety
Observe the following precautions when installing the satellite antenna. This
manual also includes other safety alerts, where appropriate, concerning specific
installation procedures.
If you work on a roof, tower, or other high structure, or use a ladder or
scaffold
to access the work site, follow these precautions to prevent personal
injury
or death:
•Walk only on sound roof structures.
•Make sure the antenna assembly and installation surface are structurally
sound so they can support all loads (equipment weight, ice, and wind).
•Use safety equipment (e.g., a lifeline) appropriate for the work location.
•Follow all manufacturer safety precautions for all safety and other
equipment used.
•Perform as many procedures as possible on the ground.
•To avoid electric shock, stay at least 20 ft away from power lines when
there is a chance that you or the equipment you are using could come
into contact with the power lines. Always look up and check for
overhead lines before moving a ladder.
•If any part of the antenna or mount assembly comes in contact with a
power line, call the local power company to remove it. Do not try to
remove it yourself.
If the antenna reflector contacts electric power lines,
you may be killed or seriously injured.
•For pole mount installations, be sure to obtain information regarding
underground utilities in the proposed location before digging.
•Call a local company that marks underground utility lines before digging
to avoid striking underground cables, pipes, or electric lines. Call 811
from anywhere in the United States to contact a local company that
does this. You can also visit http://call811.com/.
•Striking or cutting underground cables, pipes, or electric lines can cause
personal injury or property damage.
Only Hughes-certified installers may install or service Hughes antennas and
their
components. Installers must expressly acknowledge the Hughes
requirements
for Hughes installations.
Antenna installation safety
1039384-0001 Revision C 7

•Do not work in high wind or rain, or if a storm, lightning, or other
adverse weather conditions are present or approaching.
•Do not attempt to assemble, move, or mount the antenna on a windy
day. Even a slight wind can unexpectedly create sudden strong forces on
the antenna surface.
Antennas that have been improperly installed or attached to an unstable
structure are susceptible to wind damage, which can be very serious or even
life threatening
to you and the customer. The installer and the dealer assume
full responsibility that the installation is structura
lly sound to support all loads
(weight, wind, and ice) and is properly sealed against leaks.
Properly ground the antenna assembly in accordance with all local and
national
electrical codes.
Observe these precautions to avoid exposure to RF radiation, a potential
safety
hazard:
•All antennas must carry an industry-standard and government-approved
Radiation Hazard Caution label on the feed support arm.
•The antenna must be installed in a location not readily accessible to
children and in a manner that prevents human exposure to potentially
harmful levels of radiation.
•Antennas mounted in the continental United States, Puerto Rico, or a
site with an elevation angle that is 30° or greater must be installed such
that the lower lip of the reflector is at least 4 ft 5 inches above any
surface upon which a person might be expected to stand, and 3 ft 3
inches from any opening (such as a door or window) in a building or
adjacent structure.
•Antennas mounted in Canada, Alaska, Hawaii, or with a less than 30°
elevation must be installed such that the lower lip of the reflector is at
least 5 ft above any surface upon which a person might be expected to
stand, and 3 ft 3 inches from any opening (such as a door or window) in
a building or adjacent structure.
8 Antenna installation safety
1039384-0001 Revision C

•The antenna must be mounted such that no object that could
reasonably be expected to support a person is within 6 ft
7 inches of the
edges of a cylindrical space that projects outward from the antenna
reflector toward the satellite and has the same diameter as the
reflector. For example, the antenna may not be installed in a place
where the path of the cylindrical space passes immediately above a
deck on a nearby property. This reduces the likelihood of a person being
exposed to RF radiation because they stood inside of or next to that
cylindrical space.
•If the above distance requirements cannot be met, the antenna must be
mounted in a controlled area inaccessible to the general public, such as
a fenced enclosure or on a roof.
•Fenced installations must have a locked entry, and the fenced area must
be large enough to protect the general public from exposure to
potentially harmful levels of radiation.
•Access to a roof installation in a commercial, industrial, or institutional
environment must be limited by a door or a permanently fastened
ladder that is locked to deny access to the general public.
•Fenced or roof installations in commercial, industrial, or institutional
environments must carry a Radiation Hazard Caution sign on the access
door, gate, or permanently mounted access ladder within plain sight of
anyone approaching the antenna from the front or sides of the
reflector.
•Once the transmitter becomes operational, maintain a safe distance; at
least 3 ft.
Failure
to observe these cautions could result in injury to the eyes or other
personal
injury.
Observe these precautions to avoid exposure to RF radiation, a potential
safety hazard:
•
Do not remove the yellow caution label on the antenna system.
All antennas
of any type or size must carry an industry standard and government
approved Radiation Hazard Caution label on the feed support arm.
•
A fenced or roof installation in a commercial, industrial, or institutional
environment must carry a Radiation Hazard Caution sign on the access door,
gate, or permanently mounted access ladder within plain sight of anyone
approaching the antenna from the front or sides of the reflector.
Failure to observe these cautions could result in injury to eyes or other
personal injury.
Antenna installation safety
1039384-0001 Revision C 9

If the antenna or mount assembly begins to fall during the installation, do not
attempt
to catch it. Move away and let it fall.
Note: Some installations may require additional precautions. See the appropriate
site preparation and mount installation guide for more information.
