1.5.3 Interference
The antenna unit must be mounted as far as possible away from the HF antennas,
communication/navigations, VSAT systems and any high power radio transmitter (including
other Inmarsat-based systems).
Radar
It is difficult to provide the exact minimum distance between a radar and the antenna
unit due to different type of radars in terms of power, radiation pattern and operating
frequency band.
The antenna unit is recommended to be at least ±15
⁰
from the radar’s vertical beam.
The minimum radar distance indicates the minimum distance between the closest
point of the radar and the closest surface of the antenna radome. This distance is
determined by the radar, transmit frequency and the power.
