Switching from cable, I tried to become a new subscriber with DirecTV with HD and a HR-20. My lot is surrounded by trees so I figured there might be LOS issues. Sure enough, the installer said that he could get the "main" satellite, but couldn't get locals (non-HD) because of a large tree SE of my lot. Needing locals, I cancelled the installation. My questions are: 1. Does the installer's explanation make sense? I live in Cedar Rapids, Iowa if that helps. 2. Is there any way to use multiple dishes? 3. I know this is a DirecTV forum, but if a DirecTV install won't work, is it possible that a Dish Network install might?
