How to Install the Antenna Units

General considerations
• Keep the length of the antenna cable in mind when selecting a mounting location.
• Select a location with minimal or no vibration.
• The sensor should be separated more than three meters from Inmarsat F/FB anten-
nas. Select a location outside this transmission area.
• Do not loop the antenna cable or bundle the antenna cable with radio equipment
cables. When these noise reductions are insufficient, adjust the squelch on the ra-
dio equipment.
• Select a location with obstructions to the radio waves.
• Select a location more than a meter from the floor/deck etc.
• Select a location with no local vibration or impact (including sympathetic vibrations
due to engine or mast) for the GPS sensor in the antenna unit.
Installing the antenna above superstructures
It is recommended that the antenna is installed above all other superstructures on the
vessel. The antenna can obtain an unobstructed view of the available satellites, re-
gardless of the vessel heading. Failure to install the antenna above all other super-
structures can cause shadows and multipath reflection problems.
The following figure shows an example of the antenna installed above all other super-
structures.
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.
