OUTLINE OF SYSTEM
This system observes the strength of precipitation, the speed of rain clouds (Doppler speed), and observes
phenomena of rainfall.
Notice:
1. Do not go around the antenna area.
2. While installing antenna on a rooftop of building in urban area, it must be installed in the safety area and
protected by a lightning rod(s) based on IEC 62305.
3. No obstacles should be around the antenna.
Safe distance:
- If H1 is taller than 1.9 meters, it is safe unless directly touching the antenna.
- If H1 is shorter than 1.9 meters, do not enter within a radius of 7.6 meters from the antenna.
Note: It based on the standard human height of 2 meters.
- Refer the Radio Frequency Radiation Hazard on page i.
Note: It is safe to follow this calculated value because it still has some extra safer margin.
e.g.: H

(Height) = 2m,
d (Distance between center of the antenna and human) =6m, θ=2° (Minimum azimuth is -2°)
