Gents,
Although strictly not the same as the discussion above, the following article gives a good insight into the issue of end feeding antennas and the importance of keeping the phasing within close tolerances.

The end result provides excellent omnidirectional HORIZONTAL polarisation with good gain and can be extrapolated down in frequency and down in number of turns, as discussed at the end of the article.
Definitely a good read and food for thought for beacon operators.
Cheers
