4) Consider the trade off between large aperture antennas (lower maximum RF)
and small aperture antennas (lower visual impact).
5) Take special precautions to keep higher-power antennas away from accessible
areas.
6) Keep antennas at a site as for apart as possible; although this may run contrary
to local zoning requirem ents.
7) 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 fa vors co-location, but co-location can provide "challenging" RF
safety problems.
8) For roof-mounted antennas, elevate the transmitting antennas above the height
of people who may have to be on the roof.
9) 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).
10) Take special precautions for antenna sites near hospital and schools.
