Alternative grounding for steel hulls
F.3.2.2
Terminal grounded at a dedicated RF ground
(alternative)
In this case the ADU is grounded with a separate ground cable. The
ground cable must be routed parallel and close to the shielded coax
cable connecting the ADU to the ACU grounding kit. A heavy gauge
wire with tinned strands (min. 6 mm 2 ) can be used for this purpose.
Note
The ADU must be electrically isolated at its mounting bolts by
means of shoulder bushings and washers ensuring the
isolated RF ground - see Isolation of the ADU from the
mounting base on page F-12.
