Oh yes but I think what you are doing here is merely improving the contact
to the ground, which is a small part of the loss. At these wavelength this
becomes less important than the conductivity below the atenna and out to the
remote, high voltage point (hence biggest proportion of the displacement
current)of the antenna.(see theappendix of Peter Dodd's "Low Frequency
Experimenters Handbook") Again my measurements show that increased antenna
capacity by increasing the top wire loading is more advantageous, provided
this couples to the ground and not lossy "environment". I am unable to test
this over frozen ground.
