610 ITU‐T's Technical Reports and Specifications 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.
