There is only one driven element on an OWA antenna. I think the biggest
advantage is the direct 50 ohm feed. No match is needed making it easier
to build and there are no match losses. It is easy to design a yagi with a
wide bandwidth with >50 impedance however that is not referred to as OWA.

The OWA, if I recall correctly, was around before Force12 was even a gleam
in N6BT's eyes. And, again IIRC, the OWA is a monoband antenna that uses two
driven elements and specific element spacing to provide consistent gain,
matching and F/B over a greater portion of a particular band than typical.
