Hard to believe that D* would offer a dish solution that would be too large to mount on a roof, as that is where most dishes are mounted.
Still, a two-dish solution, requiring a clear line of sight to 61.5, 110, and 119, is an ugly, ugly solution for NYC, Boston, all of New England, NJ, etc., etc. That D* one large dish would have to be pretty bad to be worse than where E* seems to be headed.
