Hi Will,

Below is better than above, to say the least. How much below is
immaterial.

Is sea water equal to copper wire radials as a RF ground system?

Skip the pursuit of the Holy Grail in radials, this may lead you to
start carrying buckets of dirt which screws up buoyancy.

Why do i have to use copper foil when most other people suggest using
ordinary copper wire?

Probably more surface area.

All ideas and comments appreciated.

How good (or poor) sea water is for matching and loss, is seeing the
glass 3/4's empty. How good sea water is for propagation is seeing
the pitcher nearby and filling your glass several times.
