D.5.2 Guidelines on Arranging Antenna Locations
Observe the following guidelines when selecting the places for BTS antennas:
For roof-mounted antennas, elevate the transmitting antennas above the height of
people who may have to be on the roof.
For roof-mounted antennas, keep the transmitting antennas away from the areas
where people are most likely to be (e.g., roof access points, telephone service
points, HVAC equipment).
For roof-mounted directional antennas, place the antennas near the periphery and
point them away from the building.
Consider the trade off between large aperture antennas (lower maximum RF) and
small aperture antennas (lower visual impact).
Take special precautions to keep higher-power antennas away from accessible
areas.
Keep antennas at a site as for apart as possible; although this may run contrary to
local zoning requirements.
Take special precautions when designing "co-location" sites, where multiple
antennas owned by different companies are on the same structure. This applies
particularly to sites that include high-power broadcast (FM/TV) antennas. Local
zoning often favors co-location, but co-location can provide "challenging" RF
safety problems.
For roof-mounted antennas, elevate the transmitting antennas above the height of
people who may have to be on the roof.
For roof-mounted antennas, keep the transmitting antennas away from the areas
where people are most likely to be (e.g., roof access points, telephone service
points, HVAC equipment).
Take special precautions for antenna sites near hospital and schools.
