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.

Subject: [AFMUG] Licensed Dish RF Pattern
We were aligning an RFS 18ghz dish, and the climber said that he found a
bunch of Sidelobes as he was moving it around. I went looking for the
RF pattern of the dish to see what they looked like, with the Centerline
and the peaks and valleys going away from it, but I don't find the RF
pattern on the RFS Website. Is that something that the licensed dishes
don't do or have I just not found it yet?
