Alternative grounding for timber hulls
C.8 Alternative grounding for timber hulls
C.8.1 Grounding the terminal
The terminal must be grounded with the short antenna cable and the
Grounding kit (accessories). Further, the terminal 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
capacitive or electrical coupled). Bear in mind that the antenna ground
connection is to be made at the
same electrical ground potential
as the
terminal (see Grounding the antenna).
C.8.2 Grounding the antenna
If the mounting base of the antenna is electrically connected to any other
ground potential than the terminal (e.g. Lightning Ground), the antenna must
be isolated at its mounting bolts by means of shoulder bushes and washers -
see page 126.
However, a ground connection must be established via one of the mounting
bolts using a separate ground cable. The ground cable must be routed parallel
and in close proximity to the shielded coax cable hence connecting the
antenna to the terminal Grounding kit. A tinned heavy gauge wire (min. 6
mm
2
) can be used for this purpose - see page 123.
