4. GROUNDING AND RF PROTECTION
4-12
4.8 Alternative Grounding for Timber Hulls
4.8.1 Grounding the Communication Unit
The Communication Unit must be grounded with the short antenna cable and optional
grounding kit (S-67-127570). Further, the Communication Unit must be grounded at
its grounding stud in order to ensure a proper grounding if the short antenna cable is
disconnected.
The ground connection must be established at a dedicated RF ground (either capac-
itive or electrical coupled). Bear in mind that the antenna ground connection is to be
made at the
same electrical ground potential as the Communication Unit (see
section 4.8.2).
