For OUTDOOR use, a Directional Antenna up to a maximum gain of 11dBd is
authorized for use with this unit.
The Outside antenna must be positioned to observe minimum separation of
120 cm. (~ 4 ft.) from all users and bystanders. For the protection of personnel
working in the vicinity of outside (uplink) antennas, the following guidelines for
minimum distances between the human body and the antenna must be
observed.
The installation of an OUTDOOR antenna must be such that, under normal
conditions, all personnel cannot come within 120 cm. (~ 4 ft.) from the
outside antenna. In all installations, the antenna should never be mounted
such that the main beam is directed toward an area where workers or
bystanders may be present. Exceeding this minimum separation will
ensure that the worker or bystander does not receive RF-exposure beyond
the Maximum Permissible Exposure according to section 1.1310 i.e. limits
for General Population/Uncontrolled Exposure.
Physical Installation
The coaxial cable discussed above should be pulled from the rooftop location to the
space designated for the amplifier installation. Additional coax should be pulled from
the amplifier to where power splitters are located and thus to the position designated
for the Omni-directional antennas. Usually this is accomplished by using existing
cableways and running the cable above suspended ceilings. In many cases the
Omni-directional antennas can be located above the suspended ceilings however,
when this is not possible, alternatives such as ceiling or wall mounted antennas may
be used.
When mounting the amplifier, take care to avoid areas of high heat or extreme cold.
In general, do not place the unit on or near the top of high ceilings, by heaters or in
cold storage areas.
