A good quality 4' dish will have tighter RPE and better f/b ratio than a 2' or 3' dish. Or maybe they happened to have an extra 4' dish in stock and used it because it was "free".
If it's a new purchase of a 4' dish for a 2 to 4 mile 11 GHz link that would be pretty silly unless they need seven nines of uptime at full modulation (1024QAM 5/6 code rate?) in ITU rain zones M, N or P.
