1. MOUNTING THE UNIT

1.1

Antenna Unit

Mounting Location
• There should be no interfering object within the line-of-sight to the satellite. Objects within
line-of-sight to a satellite, for example, a mast may block transmission/reception. Mount
the antenna unit as high as possible. This keeps it free of interfering objects and water
spray. The location should be well away from a GPS antenna. A GPS receiver may be
interfered by the Inmarsat C wave.
• If both Inmarsat-B or F ship earth stations are installed, separate the Inmarsat-B/F
antenna at least 8 m.
• Separate the antenna unit from an S-band radar as follows:
• The allowable vibration level as specified by Inmarsat is as shown in the table below.
Frequency
2 to 10 Hz
10 to 100 Hz
• Avoid the location near funnels and stacks; smoke and soot on the radome can lower
signal level.
• Separate the antenna unit 5 m from HF, VHF or 27 MHz antenna.
NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating or
plastic parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.
