As I mentioned to Elliott, my education in the fundamental sciences was 
many years ago.  I didn't quite understand how entropic loss related to the 
idea of efficiency.

Googling "entropic loss" resulted in an amazing flood of incredibly 
convoluted, highly technical papers, mostly in chemistry and information 
theory.  I finally find one item that helped stimulate (ouch) some long 
unused neurons: http://www.molecularuniverse.com/Bound/bound2.htm

Entropic loss definitely occurred when Rob, K1DFT, melted his prototype 18" 
high 15m band antenna, making a transition from a solid to liquid state!

BTW, I did receive an e-mail from a friend in the Pacific Northwest who had 
a QSO with K1DFT using his patent-pending antenna on 160m.  He commented, 
"He had a nice transcon signal for 100W, but that doesn't prove anything 
about the antenna."

Sorry for the digression.

Keep clam,
