[Elecraft] How Long Is "Long Enough"?

Tue Aug 6 05:03:00 2002

Easy question to answer.  Here in the north east, if the antenna stays up
during the winter, it was not high, or long enough.

Wayne,
  I like the "tossing a wire into a tree" approach myself.  What sort of
balun do you use on the # 26 wire?

Thanks
