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

  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.

   Soon.


    Really soon...


    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....
