I want to install a ssb radio on my aluminium sailing yacht. The person who
installs the radio says that the grounding plate should be welded on the
inside of the hull. The hull is fully painted with anti fouling. He argues
that the high frequency connection to the see water is made through a
capacitor effect, the hull acting as a big capacitor, the water being the
other side and the antifouling in between is the isolator.

I hardly can believe that this works.

Is this true ?

Can this work ?

Has any one experience with SSB grounding on aluminium hulls.
