[TowerTalk] Vertical Antennas near salt-water

[Gary K9GS]

I had an interesting discussion with a friend over the weekend and 
wanted to get some input from the TowerTalk community.

Imagine a 1/4 wavelength wire hanging down from a tree with the bottom 
end attached to a post set into the salt water.  The antenna wire would 
be 3 or 4 feet above the water.  What should be done with the 
radial/counterpoise wires?  Should those wires go into the water?

Or imagine a similar hanging wire that has the bottom end attached to 
the top of a seawall.  Again, the bottom of the antenna would be 3-4 
feet above the water.  Should the radials run on the ground parallel to 
the seawall or run into the water?

A third situation would be a vertical antenna mounted at the end of a 
pier.  Run the radials back toward shore along the pier or run all of 
the radials into the water?

Finally, if the radials are in the water does it make any difference if 
the wire is insulated or not?
