Figure 2-1 Defined Radiation Areas
Hazard Area (Between the feed and reflector): This is the highest power density region
because the area of power radiation (the feed flange) is smallest.
Warning Area (Near field): This is the area bounded by a cylinder within the same
diameter of the reflector, and which extends from the reflector toward the satellite for, in
the case of auto acquire systems, less than 75 meters (the exact distance depends on
frequency and the diameter of the reflector).
Far field: This is the area situated at some distance from the antenna, where the
radiation density falls off with the square of distance.
