I was up in Anchorage a couple years ago. There were tons of dishes. It appeared that most were 1.2 meter ChannelMaster dishes. As best as I could tell, most had single LNBs on them. Some places had several dishes, but most had only one. It looked really odd because they were offset focus dishes, but they looked as if they were pointed towards the ground. Pretty shallow elevation angles.
Anyhow, it seemed like a lot of people were getting satellite TV there, so you shouldn't have much of a problem. I'd definitely want to confer with some local installers on the finer details.
