Grounding
For vessels constructed of conducting materials, run a copper strap of least 50 mm width
between the ground terminal at the base of the antenna coupler and the ship’s superstructure.
For vessels constructed of non-conducting materials, the width of the copper strap should be at
least 100 mm.

1.2.3 Mounting considerations
Outdoor installation
•
The wire from the coupler to the antenna radiates radio energy. It should be vertical as much
as possible and routed away from any grounded.
•
For optimum radio energy, locate the coupler as near to the ground as possible.
•
The length of the vertical portion of the antenna should be as long as practical.
Indoor Installation
•
Locate the unit away from GPS receivers, radio equipment, etc. to avoid mutual
interference.
•
The lead-in wire should be as near to the unit as possible.
•
Select a place where the unit can be easily maintained, but where it will not interfere with
crew or passengers.
•
Select a location where the earth connection can be made at the front of the unit.
