Re(2): [Antennas] A floating Beverage?

[DavidE Benedict]

Water will attenuate RF quite a bit, it's better a lower frequencies, but
even 
an inch or so will hose the signal. I'm not familiar with a beverage
antenna, 
but I'd assume it's just near water, not under it.

No idea is a bad idea until it is proven to be bad. 

And thinking outside the box has led to some wonderful inventions. 

But, guys, isn't ground GROUND? Impure quite water conductive?

Aren't E (RF) propagation waves caused mostly by voltage nodes...voltage
which would be very effectively shorted to ground by putting the hot wire
in the water (which with impurities is conductive)? And, where is the
other side of the coax or open-wire-line connected? ...ground, too? 

RF sometimes does the unexpected, but... ??

But, as a dreamer/inventor myself, I see your point in trying to meld all
that water with a better RF antenna or RF transmission. I hope you succeed
in a great invention!
