Does anyone know of the best (damp-proof) way to make connections to
those sintered ground plates? My woodie is fitted with a couple of
these, one for the SSB the other for the rest of the electronics and
they had already been fitted to the boat when I bought her 16 years
ago. Virtually each year I have to check and clean the connections
between the fixing studs and the 2" wide copper tapes which lead from
the wheelhouse area. Obviously these connections are in the bilge
which on a woodie is a pretty damp sort of place and this year the
ends of the copper tapes are beginning to resemble best French lace!
As a second issue, should the ground connection be RF only, blocking
any DC? Blocking capacitors are fitted at the wheelhouse termination
of the copper straps but not connected. I suppose their purpose is
to avoid recirculating currents?
