Actually, EVERY Yagi is a compromise, trading off between
Gain, F/B, SWR, Bandwidth, Size, Weight, Cost, etc.
Generally speaking, Maximum Gain, Maximum F/B, and
best 50 Ohm match (for a split dipole DE) NEVER occur
with the same design (i.e. element tuning and spacing)
for ANY Yagi regardless of the number of elements or bands.
Some designers optimize gain, some optimize pattern,
some optimize simplicity of matching. I guess that's
why there are so many different antennas / manufacturers
to choose from.
