The antenna, must be installed where:
• There is an all round clear view of the horizon.
• It is not too high above the water - the maximum recommended
height is one not exceeding half the length of the boat.
• It is as near as possible to the centerline of the boat.
• On a rigid mounting platform that is not subject to excessive
vibration.
• Away from the edge of the boat. This will minimize excessive
motion, which can adversely affect reception.

operation.
