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.
OK...so much for questions from Tokyo. Gotta get some bfst and go to work.
