Antenna installation safety
1039740-0001 Revision B
Do not work in high wind or rain; or if a storm, lightning, or other adverse
weather conditions are either 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.
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.
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.
