I'm moving into an old 1908 house that the previous owner recently rewired with a single RG-6 Coax to each room. It looks like its some sort of strange combo topography where they have used splitters in the walls to hit 8 locations, but I only see 4 cables terminating in the attic. As far as I can tell, the previous owner did NOT have Directv or Dish. Since its all the same branded RG6 cable in the 8 locations, I can only assume that they combined some of the rooms with splitters. I'm still in the process of tracing the signals to understand which attic cable leads to which rooms. I'm thinking SWM is my best option, but I have no idea what kind of splitters are in the wall. If they installed these splitters 2 years ago, what are the odds that they will work with SWM ( 2-2150 MHz)?
