There is an EXCELLENT piece of well documented research in one of
the ARRL Antenna Compendiums (Vol 4 or 5 -- I'm on the road in a
motel, so can't check) showing that the losses in typical window
line increase drastically when it is wet. As I recall, it is much
lossier than coax in that condition. Again, going from memory, I
think the author was Frank Witt.
There are several things in all of those Compendiums that make them
well worth chasing down.
