Hi,,I have a 3o inch/76cm dish set-up for Bell's 82 degree satellite on my roof near JFK airport just across the Nassau County border in Long Island, NY. My signal strength is quite good on all transponders,,from a minimum of 66 to a max of 79 with the majority in the mid 70s. I obviously need to enlarge my 91 degree dish, as well, now. Is the 91 degree footprint exactly the same as 82's? Do reports show it to be tighter northward than 82's-- worse signal for my location-- or should I expect the same signal strength on 91 as 82, or even better, perhaps, with a 30 inch/76 cm dish? Thanks for info.
