When you say "Pretty bad" - which from the list are you specifically referring to?
As I have had 3 visits now in a week with another planned for tomorrow (Thursday) I can't imagine that they are unaware of these numbers...
As for the dish itself it is on the roof about 5 feet from the eves. Perfectly clear line of sight (assuming it is pointing in the correct direction). This is Southern California - not seen a cloud in some time!
The tech yesterday replaced the LNB (at my request) and he insisted on putting in new RG-6 coax from the dish into the attic to the splitter - about 15 feet (made no difference).
In regards to alignment - is there anything I can check myself ?
