On another note, how about putting three LNBF's on a BUD?
If you recall a recent thread by Iceberg, he did one LNBF at the focus, and one LNBF off to just one side.
That was his six-foot Fortec Star dish.
I forget the spacing, but
you could probably manage 4° .
Try rearanging your bird-list a bit, and see if two dishes, with 4° birds, covering the same part of the sky, would help the problem.
In other words, get every other bird on one dish, and the remaining sats on the 2nd.
