I'm looking to add an OTA antenna to my home. Over the years, many different cable and dish installers have left thier mark on the home, prior to my ownership. In fact, a dish and all its cables are still on the house. I'm thinking of replacing the dish with an antenna in the same location and using the existing coax, since I like the way it was run.
My question is, what is this thing. (There's cables and splitters all over the side of the house that I plan to clean up.) No cables are currently connected to it that arent cut somewhere else. Do I need it? Can I use it for anything? It is properly grounded, so that's something.
Final note, I'm in a major metro area, only about 10 miles from broadcasting centers, so I don't have to be precise with my antenna placement.
