Separate ground cable
C.9.2 Ground cable - connection
The ground cable must be mounted close to and parallel to the shielded coax
cable thus minimizing ground loop problems. If possible, route the coax cable
and the ground cable in metal conduits bonded to the hull or within a mast
(depending on the actual installation).
The ground cable must be connected at one of the mounting/grounding bolts
on the antenna. Use bolts and washers of stainless steel and seal the joint
with protective coating to avoid corrosion. If the antenna is to be isolated from
the mounting base, shoulder bushings and washers must be used - see
page 169.
In the below drawing, vibration isolators are mounted.
At the other end, connect the ground cable at the terminal grounding kit as
described in
