Think about wiring your cable runs with 1" flexible plastic carlon conduit to your boxes/openings for them. That way as cable requirements change over the years, it will be easy to fish new cable etc. I forsee new changes where you may have one or more fiberoptic cables or something else instead of what is being used now. The old bulky multiwire stuff I've run for the 10' C band dishes with wires for the rotator and limit switches and feed cables is now all history to be pulled out. We went from rg59 to rg6 as recommended cable runs and it will change again. We went from bell wire to cat3 and now cat5 telephone wire with 2 to 4 twisted pairs and that will probably change too.
