I suspect that the Isotron performs best when the
feedline is radiating like crazy.

That's consistent with the installation instructions that state that
it must be mounted on a metal mast.

So the question
is: Has anyone ever tried to maximize feedline
radiation? Seems that is what the Carolina Windom
has done by accident. Can it be done on purpose?

Use a simple wire or rod radiator tied to the center conductor of the
coax, no radiator tied to the shield, and a length of feedline which
is an even multiple of a halfwave (at the exterior shield's
velocity-of-propagation) back to ground or the transmitter, serving as
a counterpoise?
