Assuming you are going with a tripod based antenna and a Genie (HR44) you just need a dedicated run from outside to where the HR44 will be located. Your existing cable input will not work but there is a chance it could be modified.
If you want 2 TV's running the best option is to have a dedicated cable to each which needs to happen AFTER the SWM splitter. If you don't have a way of doing that then you will need the Genie, a wireless video bridge connected to the Genie and a wireless client for the 2nd TV. The wireless bridge needs to be located at least 4' from the Genie (unless that has changed recently) and the Genie and the Bridge must be at least 4 feet from the client.
You will need the antenna (be sure it's a SWM3 LNB) and a direct run to the Genie. If you want to make 2 direct runs to the Genie and a WIRED client then you will also need a 2 port splitter (or 4 of which you use 2) and a dedicated coax run from the splitter to the client but you would NOT need the Video Bridge.
