Abby said:wow. I have in my house DTV. I did a major install myself. But the dishnetwork is my friends. I know nothing about it. I was just trying to help him out. I thought it might be a lot like DTV. All I know is he has 4 irds hookup now. He wants to add a 5th. I can only find 1 of the 4 hookups. Can I just add a switch to that line?
