The only point on my lot where I can put my Direct TV dish is 350 feet from the house (hilly lot - tried everything, no luck). Dish is receiving crystal clear HD signal, but I can't get any HD at the house (too far away). Non-HD channels work fine, but all HD channels show error message - something like "771 searching for signal ...." I've had three different techs out to look at it - nothing. Totally SUCKS, but it sounds like I'm just f'ed.
