DISH here, I have only lost signal twice, both times for just a matter of a minute or two and during horrendous rain storms. No ice or snow here. My installer told me some of the same stuff mentioned above. Primarily that how well your dish is pointed makes a huge difference.
I have been very pleased with DISH!
