I don't have clear access to the sky to pickup all Dish satellites with one 1002.wa. I have three holes in the conifer canopy that will allow three different dishes mounted in three different locations (100ft from rcvr) to each access a single satellite of the trio. If I combine thru a switch, would this setup work on a single Hopper DVR? Does each dish need to point to a specific LNB? or can the center one be used on all of them?
