Antenna alignment
Each antenna is aimed directly at, and has an optical line-of-sight radio path
to, the antenna on the other end of the link. The presence of buildings, foliage
or other obstructions within the radio path or the first Fresnel zone will
impede performance and could prevent communications. Depending upon the
antenna diameter used, the beam width of most of the transmitted signal will
be 5 degrees or less, requiring that the antenna be accurately aimed.
A quality magnetic compass and spirit level be should be used to aim the
antenna. The azimuth of the other site must be known and magnetic deflection
considered. You can consult topographical maps to determine the amount of
local magnetic deflection.
The antenna mounting hardware can be adjusted after the antenna is installed.
To use the adjusting points, the clamping bolts must be slightly loose. After
the antenna is aligned for maximum signal strength, tighten the mounting
bolts.
The antenna is connected to earth ground using #6 AWG copper ground wire,
in compliance with local and national electrical codes.
WARNING!
There is no proven link between the low level of RF emitted by
this device to any type of injury or disease, however, it is
recommended that you follow these precautions to minimize
unnecessary RF exposure:
• Do not connect power to the IDU and do not install the cable
between the IDU and ODU until the antenna and ODU are
installed. This will prevent radiation from the antenna when
people are within close proximity.
• Do not install the antenna where it is possible for a person to
stand within five feet of the radiating side.
ODU installation
There are two versions of the ODU, labeled A and B. Each SkyZhone 45
system must have one A variant ODU and one B variant ODU. The A version
transmits on frequencies between 5.725 and 5.825 GHz, and receives on
frequencies between 5.250 and 5.350 GHz. The B version transmits on the
lower frequencies and receives on the higher.
Either variant can be used at either end of a link, however, it is recommended
that the A variant be installed on the end of the link that is nearest the Central
Office.
