It ain't no turnstile.
Yep.Homer, on second look I think you are right. Back to the drawing board.
Yea, using a 1 : 1 balun on those 1/2 wave legs was the first thing I thought was out of sorts..If the elements were half as long, it would be a turnstile antenna of some sort.
But half-wave long wires should give it a horrendously high feedpoint impedance.
