Hi, I'm new to the forums. I did a search but didn't find anything that seemed relevant to my question. I'm getting HD with a DVR installed today, and want to know what kind of signal strength I should be looking for when he sets me up. I don't want the installer to leave the house until my numbers are good-I know sometimes these guys are in a hurry and don't necessarily try to get things as good as they can be. I never ask myself "is it good enough?", I ask "can it be better than it is?"
