CAUTION
Observe these precautions to avoid exposure to RF radiation, a
potential safety hazard:
• 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 Puerto Rico, the continental United
States, or at any site with a greater than 30° elevation angle
must be installed such that the lower lip of the antenna
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.
• Antennas mounted in Canada, Alaska, Hawaii, or any site
with a less than 30° elevation must be installed such that the
lower lip of the antenna reflector is at least 5 ft 9 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.
• 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 projecting
outward from the antenna reflector toward the satellite.
• 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 a roof.
• A fenced installation 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.
• Once the transmitter becomes operational, maintain a safe
distance; at least 3 feet.
Failure to observe these cautions could result in injury to eyes or
other personal injury.
