Installing and Adjusting the Antenna
The installation information discussed in this
section is generic. For installation procedures
specific to the antenna you are installing, refer
to the antenna manufacturer’s documentation.
Antenna Installation
WARNING
(FCC requirement for implementation in the USA)
Antennas used for the transmitter must be fix-
mounted on outdoor permanent structures with
a separation distance of at least 2 meters from
all persons during normal operation. Antennas
must be professionally installed. Installers must
be provided with antenna installation instruct-
tions and transmitter operating conditions,
including antenna co-location requirements of
CFR47 Part 1.1307(b)(3), for satisfying RF
exposure compliance.
Antenna installation consists of permanently
mounting the antenna to the mast, pole, or
tower and then attaching the RF Unit (BSU or
SU) to it.
The antenna and RF Unit must be mounted
outdoors on a tower, building roof, or other
location that provides line-of-sight path
clearance to the far-end location. In some
cases, the antenna can be mounted indoors,
behind a window; however, RF attenuation
through windows can vary greatly, depending
upon the glass and any coatings that might be
present, plus the precise location and angle of
the antenna relative to the window.
In cases of indoor installations, ensure that the
antenna location is restricted and bear in mind
the RF exposure requirements of the warning
statement above.
Antennas should be:
▪ Ordered with the suitable mounting kit
specific to the site requirements.
▪ Very rigidly mounted, with adequate room
for azimuth and elevation adjustment from
the rear.
The antenna polarization must be the same at
both ends of the link, either vertical or
horizontal.
In general, antenna mountings require a support
pipe to which upper and lower support brackets
are attached with U-bolts. The antenna and
optional elevation and azimuth adjustment rods
are then mounted onto the support brackets.
The entire structure must be adequately
grounded for lightning protection. The antenna
system must always be installed according to
the manufacturer's instructions.
Alignment Guidelines
When aligning antennas, if the SU is located
indoors or distant from the antenna location,
you may want to use a cellular telephone or
two-way radio for relaying signal strength
information from the SU Utility software to the
antenna alignment location.
Similarly, a cellular telephone or two-way radio
can be used to relay received signal strength
information at the SU to the BSU alignment end.
