The installer will have to get a doube strand of cable from the dish to your home run. From there it's up to him to decide how he wants to do it. Probably the best thing to do would be to diplex it for the TV2 feeds. I know it sounds more complicated than it really is. The only thing YOU have to worry about is how your installer will get 2 lines to your home run from outside. The rest is up to him. It's not that hard.
