Another thing to think though is using the existing cable from the dish install.

Cable and dish installers are notorious for being poorly trained, low pay and just get it over with attitudes. (They get a flat fee for everything they do, and it's not much to start with.)

None of that matters with cable or dish reception because the signals are very strong and flat. So bad connections, long runs, etc, won't noticeably degrade your reception. I've seen installs from cable guys with 4 separate splitters piggy backed on each other. Totally killed reception at the 3rd and 4th TV when using an antenna even when the first TV got everything the home owner wanted.

Over the air reception is very much affected by such things as bad connections, long cable runs, number and type of splitters, etc.

Start with just one TV and as short a new cable as you can to find and fine tune where you put the antenna. Work from there to determine if and which cable run you can use and which ones you may have to replace.
