[TowerTalk] balloon supported antenna

[ve4xt at mts.net]

Or,
Run the bottom part of the 1/2-wavelength antenna away from the vertical for 30 feet or so and feed it 
at the corner as an OCF vertical...

Then, you have less wire to hold aloft and no feedline to hold aloft.

Would make an interesting model to study.
