I went and found my JRC 2000 radar manual. It has a 25 mile phased antenna aray and the following was exerpted from its manual:
"When mounting the Radome to a platform attached to a fly bridge, or superstructure, avoid placing the Radome Unit at eye level. Although the radar transmits a 2.0 kW peak power the average power radiated is less than 0.5 W. Therefore, the hazard from RF radiation levels is virtually nonexistent beyond 2 feet
from the Radome Unit. However, due to the sensitivity of the human eye, it is recommended and prudent
to install the Radome in a plane above or below the passengers line-ofsight."
