HELP!!! I've been a DirectTV customer for some time and considered myself fairly knowledgable with the basics of system setup/troubleshooting. I've pulled an older single LNB (dual output) 18x20 "round" dish and installed at my farm. Brought a box from my system at home and cant get it working. (UGH!!) Even transponder readings in the low - mid 90's. Is it my LNB? Is the LNB/dish not compatable with my D11 single input receiver? Is there a test to figure this out? I'm FRUSTRATED AND AT WITS END. Any ideas, suggestions would be greatly appreciated.
