Booty, at first glance I thought that looked like a reasonable example, but now I'm not so sure.  To me it looks like a dual coil ¼λ antenna with a top hat for additional loading.  I don't see the current node actually being moved any with that design, although I could be wrong.  If the loads plus the top hat looked large enough to add enough electrical length to make it a ½λ overall perhaps, but they just don't look like they would to me.
