This is true, of course, but an even more important advantage, IMO, is take-off
angle diversity; simply by switching from both antennas to the bottom one, I
often find that it will revitalize a European run that had seemed to be drying
up. Top-only does not have the same effect, because the center of the first
lobe is still at the same angle as the stack, or very close to it.
