Even thought it looks bizarre, many dishes can be turned upside down (feed
arm at the top) to get them to operate down to 0 degrees.
It depends on your dish. I think it does work for both the PrimeStar's out
there and the DSS/Dish Network dishes. But I could be wrong on the DSS
dishes.
Otherwise making a block of wood that is 22.5 degrees in angle and mounting
the dish to that and the block to the rotor can also correct for the offset
angle.
