Now to the original question, in spite of the data in QST, I have
found spreads of less than 15 feet in a practical environment will
not achieve your goal. YMMV.


Again, thanks for the comments. For clarification, though, could you
describe what you mean by the 15 feet spread for a 75M antenna? The QST
author is describing a biconical antenna with two dipoles tied common at
the feedpoint, but spreading out a couple degrees to the ends.... his
figures indicating 6 feet at the ends working, but 15 feet the spread if
using the recommended 2.8 degree angle from the apex.

Is this what you mean, or are you describing two dipoles separated their
full length by 15 feet?
