Default Supporting 450 ohm feeders across an open area

I am looking for a way to run 450 ohm wire to a tower approximately 50
feet away from the shack. The tower is only 32 feet high, but I plan
on doing one of Cebik's (or is it Cecil's) rotatable 44 foot dipoles
fed with open wire feeders. I'm wondering what some of you have done
to support a run of open wire feeders to stop it from flopping in the
wind. Thread some rope through the windows of the feed line? Thanks.

Terry,
Ever seen the 'ribbon' type banners? When you do, you'll notice they are
twisted to
form sort of a spiral. Part of the reason is because the 'spiral' sort of
averages the
ribbon's cross-area over a long span. Do the same with your ladder line,
twist it. It'll
still flop around a little but nothing like a straight run of it will.
How to support it over a 50 foot span? Depending on the size of
conductors used,
it ought to support it's self. There's no real need for large conductors,
either. A #18
hard drawn copper wire will support much more than it's own weight.
Shouldn't be a
problem unless you hhappen to get some very high winds...
'Doc
