I signed up for Dish a few weeks ago. After the installer left I noticed I didn't have my local channels that I asked for. I was told that I need a second dish to get these and they're coming out this Friday to install it. Why is it that I need 2 dishes? My friend has Direct TV and doesn't need 2 dishes. If this is the case I'll be switching to DTV, last thing I need is my house looking like a NASA communications center.
