In one of the excellent ARRL Antenna Compendiums, Frank Witt published 
the result of his research (including careful measurements) of loss in 
open wire line and window line when it gets wet.  Frank is a real 
engineer.  W1ZR is not -- he is a writer, and his writing in QST is full 
of technical errors.
