Off top my head, it would seem the slant wire would work to create a
directional effect of one sort or other, depending on the specifics, but I
have no clue why the FCC dissed that one.  They usually attach some
technical explanation to rulings.  You have access to the specific
proceedings?  I could come up with a dozen speculations about it, but
that's all they'd be.
