Waxing about old ham lore, a "Strays" item on page 132 of the December 1946 QST has W6KA repeating advice from W3LPY and W1MJH that "Simonizing" 300 ohm line (or using floor wax) will "eliminate the impedance change during rainy weather."

p.s.- That would be the impedance presented to the transmitter which changes, not the characteristic impedance of the line.

Based on my measurements and method I used to measure 100 ft of window line, the loss in the line from dry to wet is frankly nil. However, the wet line does show a velocity factory change, in effect an electrical change in line length, and thus when connected to an antenna, will have a small effect on the impedance at the station end of the line.

I really think and believe many comments and opinions regarding window line, are more "old ham lore" not based on true and complete facts.
