This isn't much help but I also saw a vertical (or horizontal) wire design
made from a good quality 300 ohm TV line. The interesting thing is that it
was closed like a folded dipole only the feed was 50 ohm coax. The feed was
not in the middle which is a 300 ohm impedance but off-center where the feed
impedance was close to 50 ohms. I'm not sure about the length of the
antenna or the location of the 50-ohm feedpoint.
