The Mojo is in the sea water which has a conductivity
of about 500 millimhos/per meter. The best of soils
are about 30 millimhos/meter and average soil about 5
mmhos/meter. A small island is as near to a perfect
ground plane as you will find.

I agree!
For verticals there's a 2 or 3-fold effect:
1a vertical over sea water will have very much reduced losses in the
near field, ie close to the antenna so increasing its efficiency, ie raising
the 'power output' compared to a land situation
2the increased conductivity in the far field

I agree! Although the K3 is a great radio, 90% of the mojo is antennas and
location. If you are really interested in the secret of vertical antennas
