Open Wire Line

I have been using balanced line for years to feed various antenna configurations here at the station. Originally, with lighter power handling requirements, I used the 450 Ohm #14 “window line” which sort of works but at a tremendous cost due to the marginal dielectric and its cross section to conductor ratio. That resulted in tremendous swings in matching because of rain, whipping around in the wind, and even heating in the sun.
