I’m not convinced that one can arrive at the same levels for a Yagi-Uda though, which I believe was mentioned earlier. You can compute a capture area, which is itself not circular.
I have thought about trying to reduce the first sidelobe on a Yagi-Uda type antenna, perhaps with a small bend on the ends of the elements. I personally find that sidelobe annoying as if one knows the general direction of a station one can rotate the beam and think one has the peak but doesn’t.
You can argue sidelobes are advantageous in a contest.
Anyway, I will not take the argument too far from the dish. Yagis are a quite different beast.
