Antenna Siting
When siting antennas, consider the following points:
A site with a clear line of sight to the remote radio is recommended. Pay particular attention to trees,
buildings, and other obstructions close to the antenna site.
Example of a clear line-of-sight path
Any large flat areas that reflect RF energy along the link path, for instance, water, could cause multipath
fading. If the link path crosses a feature that is likely to cause RF reflections, shield the antenna from the
reflected signals by positioning it on the far side of the roof of the equipment shelter or other structure.
Example of a mid-path reflection path
The antenna site should be as far as possible from other potential sources of RF interference such as
electrical equipment, power lines and roads. The antenna site should be as close as possible to the
equipment shelter.
Wide angle and zoom photographs taken at the proposed antenna location (looking down the proposed path),
can be useful when considering the best mounting positions.
