CAUTION
Observe these precautions to avoid exposure to RF
radiation, a potential safety hazard:
The antenna must be installed in a location or manner
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 greater than a 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 in. 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 less than a 30° elevation must be installed such
that the lower lip of the antenna reflector is at least
5
ft 9 in. above any surface upon which a person might
be expected to stand, and 3 ft 3 in. from any opening
(such as a door or window) in a building or adjacent
structure.
The antenna must be mounted such that no object
which could reasonably be expected to support a
person is within 6 ft 7 in. of the edges of a cylindrical
space extending from the antenna reflector.
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.
The antenna must be mounted such that there is no
object outside the controlled area which could
reasonably be expected to support a person within
6
ft 7 in. of the edges of a cylindrical space extending
from the antenna reflector.
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.
Failure to observe these cautions could result in injury to
eyes or other personal injury.
