My measurements, posted on this newsgroup some time ago and also

the measurements involve detergent of any kind.
Who was it who published loss data based on laying the ladder-line
on a wooden deck and/or squirting a wetting agent on it? Did you
use a wetting agent?
So what we're saying is that if it rains really hard (horizontal rain)
and the rain happens to contain detergent, then that experimental result
is valid! 8^)
I've had a ladder line fed antenna up for a couple years, and noted no
difference between rainy and dry operation.
