Y'all might want to more closely re-read the original post..... we'll
wait for ya...

Now Hear This:
Somewhere in the middle of this grand affair, Brett attaches a length of
(homemade) 'ladderline' to the end of the two coaxial cables - the
ladderline then proceeds to the feedpoint of the antenna. The "balanced
coax" does not.
I'm looking at the coax as a specific set of impedances distributed
along the length, with possible effects from any interaction between them,
especially at the E and H nodes...
Right now, as you say, it's 'speculation' - but I've found some
interesting things to explore, and I intend to trek that trail.
In closing I offer you the example of a coax balun... it's just a run
of coax - so what if it's coiled in a solenoid? Its still coax....
