I'm currently planning my SSB installation
and I am using special copper paint
for my ground plane (just like using copper plates). However I cannot find 3 square metres of floor under the sea level. I have a number of options but perhaps the best is the lazarette. However only about 1 square metre is beneath the sea level and actually touching the sea. The rest is either above the sea level or on a wall not touching the sea. Does this matter? Will I only get 1 square metre's worth of grounding, even if all 3 sqaure metres is painted?
Any help appreciated.
