The antenna is installed in a controlled location access is restricted to authorized personnel only. The antenna is marked with RF Radiation Hazard signage. 2. Inside the controlled area, MPE levels exceed the MPE exposure for occupational levels. The levels will be reduced to safe MPE by removing power to the transmitters when work is performed on or around the antenna. This area can only be accessed by qualified personnel. 3. The field develops 15 meters above ground level at the minimum elevation angle which is not accessable to the general public. Generated 7/19/2016 1 of 1 rad haz auto report-tk-mod WAAS
