Having  just spent time explaining to a guy named Yagi that his name was 
famous, I had two hours on trains to ponder the snow static thing.  
Because the quad avoids the corona problems of the yagi and lpda at high power 
and high altitudes, it is not unreasonable to think that that same attribute of 
the closed loop would also reduce snow and rain induced static at lower power 
levels.   Let me append a question mark to that...I'd be interested in thoughts.
I don't buy the "radome" effect notion, though.  I'm not made of aluminum, but 
I can build up a lot of charge walking across a carpet in New Mexico, and have 
an ESD event spanning close to an inch.  (> 1 mile above sea level).   
Eventually, any charge buildup on the structure due to moving snow or rain 
particles will have to be drained off.  
When that happens, what's the current path?   Down the conductors to the spool 
holding the BeCu tapes?   Is that grounded?   IF it's grounded, then it may 
bleed off continuously, as it would for plummer's delight yagis, with grounded 
elements.  Somebody might want to ask the Mertel's.  I'm sure they'll tell you. 
Which brings me to a corollary question...has anyone had first-hand comparison 
abilities between plummer's delight monobanders, and an array with floating 
elements, like a kt34a, for example?   I'd be interested in the snow/rain 
static answer if so.
I've heard the differences in snow static on tall arrays...where the higher 
antenna has been much noisier than the lower ones.   Pretty sure that's true, 
although I'd like to see a theory as to why. much for questions from Tokyo.   Gotta get some bfst and go to work.
