That's what Wes built to compare with the window line. Most practical 
implementations of open wire line use much wider spacing. The increased 
loss that Wes measured was due to water on the un-windowed parts of the 
window line -- in other words, a significant fraction of the dielectric 
between the conductors was water. That would not be true of widely 
spaced wire, insulated or not.
