I'd make sure the dish is located where you can easily clean the snow off if that's a problem. Make sure all lines from the dish are located in a common location in the house. This allows for easier expansion. If you're getting an SWMLine dish then there will only be one line, otherwise 4. If possible scope out your house for where the lines could be run. If not an SWM install, then each DVR will require 2 lines. Have all room lines home run to the same location of where the dish line is.
