In building a 1/2 wave dipole 4 SQR 40 meter array, the answer to this
question was critical in my understanding of why the positive side of the
dipole went up and why the distance between the tops of the dipoles (ends of
the positivie side) was critical in making the array a better performer.
Bringing the tips of the dipoles out away from one another and positioning
them over the feedpoints made the average spacing between elements improve
the array. It also helped me understand why the bottom of the dipoles
(negaitive side) could be positioned to better fit my tower installation
without the distance between them being as critical. Understanding 1/2 wave
dipole theory, as it pertained to where the antenna radiated most of it's
energy, was important. In practice, moving the tips of the top of the
dipoles away from each other made the array better by improving the F/B and
making it more efficient, explained by the radiation pattern of the 1/2 wave
dipoles. I think it was/is a good topic for TT.
