v60E - Maritime VSAT Antenna System
4.1.2 Avoiding RF Interference
Do not install the antenna near the high power shortwave radar. Most radar transmitters emit RF energy
within an elevation range of -15° to +15°. For this reason, it is recommended to position the antenna at least
4.6 m (15.09 feet) away from the radar.
Figure 2: Potential RF Interference
WARNING
Never place the antenna in the beam path of the radar regardless of distance. The high power
shortwave radar may impair its performance or damage the antenna.

4.1.3 RF Hazard Precautions
The antenna is designed to be used with radiation transmitting equipment manufactured by others.
Exposure to RF radiation, including exposure associated with an improper use of the transmit equipment,
may be hazardous to persons close to the above deck unit. Ensure the safety of personnel who work on the
system.
During transmission, ensure to keep the minimum safety distance. The recommended minimum safety
distance to the reector on the focal line is about 30 m (98 ft), based on a radiation level of 1 mW/cm that
applies under uncontrolled environment. No hazard exists >20° below the antenna's mounting plane.
