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
