Omnidirectional coverage
These antennas radiate RF energy
equally in all directions in the horizontal
plane. The antenna input power is
typically 10 – 80 watts, and the
compliance boundary for a worker
typically extends 0.1 – 1.5 meters from
the antenna.

Sector coverage
These antennas restrict most of their
radiated RF energy to a narrow angular
sector in their forward direction
(typically 60 to 120 degrees in the
horizontal plane, typically 8 to 14
degrees in the vertical plane). The
photograph shows two sector antennas,
one mounted above the other. The
antenna input power is typically 10 – 80
watts, and the compliance boundary for
a worker extends typically 0.2 – 3
meters from the front face of the
antenna.

In the diagram, the compliance zone is
shown conservatively as covering the
full height of the antenna; however, due
to the vertical antenna pattern beam
width the exclusion zone boundary may
be narrower in the vertical direction.

Where antennas are mounted on the
exterior wall of a building, there is
typically no compliance zone within the
building to the rear of the antenna.
