3.3.2.5
Line Of Sight (LOS)
The LOS is a straight line between the antenna and the satellite. This line is typically
obstructed by the ship’s funnels and masts.
Ideally, there should be no obstructions to the LOS, with a clear view of the satellite in all
directions. However, it is usually necessary to compromise between the LOS and other
considerations.
3.3.2.6
Radiation and Interference
The mounting location should be as far as possible and on a different level from high-
power radar systems or other radiating devices.
The OceanTRx™4-500 system complies with the IEC 60945 standard. The installation
should be planned to prevent any disturbing radiation that exceeds this standard.
Where there is difficulty calculating the correct conditions, it is recommended to
maintain a distance of 10m and 10
°
from the main lobe of any radar.

Radome Support (Mast) Requirements
It is the responsibility of the customer to provide the support structure (eg. mast) on
which the antenna system will be mounted.
This section describes the minimum requirements for this structure, provides a detailed
example and includes the mounting holes to the deck.
