It's been eons since I've had Dish. When I had it they only had 119 and 61.5, and I think 61.5 was only for Sky Angel.
I've had DirecTv since 2001 and went from dual tuner to a SWM system.
In my installation, I have nothing in the way of LOS, so rain has never been an issue aside from the heavy downpour's I'd just laugh at cable's commercials about watching movies on a rainy day and how it was impossible with satellite.
Generally, we lose signal just before a storm comes, the signal comes back just as it starts to rain, and then drops out again as the heavy rain comes.
In all the comparisons I've done, to match our Choice Xtra Classic package, we would have to get one of the highest packages Dish offers which does not equate to any savings.
