Alternative grounding for steel hulls
B-6 Appendix B: Grounding and RF protection 98-137654-A
B.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 B-12.
