I think what these spec sheets do not do a good job of explaining, is that
there is a bullseye pattern situated around the main lobe. This means that
if you scan left and right, or up and down.. you should find a secondary
peak about -10db lower in each of the 4 directions when properly aligned.
In
Nate,
I think this is the radiation pattern envelope that you were looking for. Keep
in-mind that the RPE is “smoothed” over the peaks and does not show the valleys.

There will be a pattern. I would normally expect them to be in the brochure
or spec sheet for the antenna.
But parabolic dishes all have a very similar set of sidelobes. First set of
sidelobes are down 20 dB or so from the main. And are a couuple of degrees
away from the main boresight lobe.
