Alternative grounding for steel hulls
61
Terminal grounded at a dedicated RF ground (alternative)
In this case the antenna is grounded with a separate ground cable. The ground cable must be
routed parallel and close to the shielded coax cable connecting the antenna to the terminal
grounding kit. A tinned heavy gauge wire (min. 6 mm2) can be used for this purpose - see
page 64.
Note
The antenna must be electrically isolated at its mounting bolts by means of shoulder
bushes and washers ensuring the isolated RF ground - see page 67.
