So much for my memory! Should have consulted "Yagi Antenna Design"
by Jim Lawson first. Pete is correct.....F/B falls off more slowly
above resonance with a 2 el reflector design.
What I was trying to remember is that the gain peak and F/B peak do
not occur at the same frequency. With a 2el reflector Yagi, the gain
peak is below the F/B peak so tuning it a bit higher can provide some
benefit. With only 2 elements, everything is a bit of a compromise.
