[TowerTalk] balloon supported antenna

[Dave AA6YQ]

1 foot of 450 ohm ladder line weighs .4 oz, so 500 feet would be ~12.5 lbs,
which seems feasible.

      73,

          Dave, AA6YQ

I don't think there is a balloon out there that will hold up 460 feet of
RG213...


Even multiple balloons would have a tough time of that.

And the coax should come away from the feed point at 90 degrees for ~1/4
wave...
