Not mentioned in the discussion:

For 2 elements, a driven array can be tuned up for really high
F/B ratio, like 20 to 30 dB, maybe even 40 dB on a good day.
A 2 element Yagi will never do more than 10 dB or so F/B.

On receive, a 2 element driven will have a pattern very close
to a 3 element Yagi.  Often, receiving on 80 is the limiting
factor.

Thanks for the advice. Looks like best way to achieve the results will be
to feed them both instead of parasitic array. Hopefully have boom up
tommorow then start playing.
