Looking at building a new house and had a couple things I figured someone here more knowledgeable about installs might be able to answer. We don't want to have any wires running on the outside of the house, so we figured we'd have an external jack mounted in the eve that goes back to the network/TV panel where we do all the cross connects. The attached picture shows the what I think are the best locations for mounting. The two blue spots marked are my preferred locations, just not sure if a roof mount or side wall mount is preferred or required. The view in the picture is from almost exactly south, maybe just a little more from the west. The yellow marked roof above will be solar panels, and the wall at the red box is where the comm closet and all coax/network cables will be centrally located. My main concerns are what type of external jack to use, and what the requirements are for grounding before/at the penetration. Don't want to get everything installed and realize that something was overlooked that would make an installer say no and either want to put a new hole in the house somewhere or just walk away. BTW, not the actual house in the picture, just the same design with pretty much the same orientation, but a couple blocks away. Construction hasn't begun yet. Another quick thing I haven't been able to find a straight answer on after some quick searching. Can an antenna installed in the attic area below the solar panels be diplexed into the SWM setup and taken to different areas of the house with a single wire? Or do I need two coax? Thanks taking a look and for any advice you might have.
