I guess I was being a little picky, but the sentence literally said that
the *folded dipole* in addition to other unique properties rejected
even-ordered harmonics, implying that this was yet another property unique
to the folded dipole.

Of course, the behavior of any dipole that you summarized is correct and
well-known.
