2. INSTALLING THE SYSTEM

Extending the ground plane
In some cases it may not be possible to access the hull and at the same time place
the Communication Unit in a suitable place.
A way to insure good grounding and at the same time make it possible to ground the
coax cable - is to extend the ship ground plane by means of copper foil. The maximum
length of the foil is determined by the width of the foil.
Copper foil 5 cm wide: Max 50 cm
Copper foil 10 cm wide: Max 100 cm
Copper foil 20 cm wide: Max 200 cm
Note: The foil must be at least 0.1 mm thick.
Connect the foil to the hull by plenty of screws or hard–soldering. Run the foil past the
place where the short antenna cable is to be grounded and mount a grounding kit on
top of the foil. A suitable grounding kit (S-67-127570) is optionally supplied.
For further grounding information read chapter 4.
2.5.3 Cable support system
The Communication Unit is shipped with a cable support system attached.
It is a simple system to which you can secure your cables using cable ties.
