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.
and, the trade, as always, is that the gain is slightly less, and the
F/B & F/R (aka sidelobe levels) will be worse, particularly at band edges
