Grounding Recommendations
illustration below. The crimp terminals must be a marine approved type e.g. the
DuraSeal series from Raychem.
Ground cable - connection
Mount the ground cable 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
ADU. Use bolts and washers of stainless steel and seal the joint with protective coating
to avoid corrosion. If the ADU is to be isolated from the mounting base, shoulder
bushings and washers must be used — see figure E-7, Isolation of the ADU from the
mounting base on page E-8.
At the other end, connect the ground cable as described in To ground the BDU on
page E-2.
Isolation of the ADU from the mounting base
In cases where the ADU is to be isolated from the mounting base, shoulder bushings
and washers (accessories) must be used as illustrated below. Please note that the
