I want to thank you all for the comments, I gathered all the info and will
now do some testing. If this works I might even be able to put some at my
contest station in Portugal CR6K.
Once again thank you to everyone for sharing each one's knowledge.
Happy Easter to all.

One time in Jamaica I ran a test between two 10m verticals: one right on

Per ARRL the K3LC NCJ work is unobtanium. (WHY?) A Google search
yielded nothing. If a member has pdf's of the articles or a link,
forwarding them to me would be much appreciated.

I did not recall seeing tests for verticals a wavelength or more way from
the sea so I checked the team vertical website and found the following:

While field testing the verticals this past summer, we decided to test the
effect of the land-water boundary on the pseudo Brewster angle.
The problem John, with that experiment is it does not tell you what is
happening just above the very lowest angle. By modelling you can see that
the last lobe to reduce is that contained down near the horizon. We are also
interested in the content between 2 degrees up to 20+ degrees. By moving the

Incredible signals, peaking S9, I not remember hearing such signals from
Europe!

This is fascinating stuff. My 160 meter vertical is less than 2
wavelengths away from the Great Pond Bay and the salt water lagoon
inside which includes a floodplain of very brackish water. This is
proven my taste and by the fact that there are plenty of mangroves
there. Before I knew any
