[Antennas] Fractenna in the news...

[K1TTT]

Since the gain has to come from a change in pattern, and they make some
reference to not showing the vertical pattern, I would assume that the
diameter of the sleeve is somehow related to the frequency and causes
cancellation in the vertical plane... while this is good as long as you can
stand having a fatter monopole, it probably wouldn't scale well to HF.
