I know very little about satellite tv. I am trying to hook it up at a tailgate. I have a direct tv dish and my in-laws dish network receiver. I also have a dish network dish but it has no lnb. Can I hook up the direct tv satellite and dish network receiver and get a signal? If not, can I take the lnb from the direct tv satellite and hook it up to the dish network satellite? Is this lnb compatible? If not, any ideas where I can buy a lnb compatible with a dish network satellite dish? Thanks alot for the help. As you can see, I'm an idiot when it comes to dish tv.
