Bill is correct about the loss of service. There are programs that precisely calculate loss of service, in time, per year (and its usually minutes) based on the size of the reflector, the satellite and transponder, and most important, the location of the user. There are very complex algorithms that add all this up, and based on where the user is located, factor in typical and averaged weather to spit out that loss of service time.
I have programs to do this terrestrially, but not with satellites. It would be interesting if the engineering folks at Winegard had this data to share. Then you would really know what to expect.
Got any friends over there Bill?
