No, it's not. Re-read my description. It's also not new -- these designs 
have been around in one form or another for years, but most hams, me 
included, are lazy about doing the engineering to build them ourselves, 
so we buy another guy's work.   Now that I'm retired, I AM doing more of 
my own design work, rather than buying another guy's work.  BTW -- if 
you read my piece on Antennas For Limited Space, you'll find a reference 
to a piece in QST roughly 6 years ago on exactly this sort of design. 
Written by a Frenchman, if I recall.
