Hey guys, Everyone here seems like pretty smart folks when it comes to satellite setup so hopefully you guys can please help me out. I have Direct at home with an HD DVR boxing the living room and a H24-700 hooked up in the bedroom. On the roof, is a Slim dish and the whole thing is set up with a Swm system. I decided I wanted to take the leap and set up a TV for tailgating this year. So I got an old 18 inch dish from a friend (18LNBR1-01) and I've tried hooking it up in the backyard to the H24 box with no success. The box is telling me it can't get a signal from the dish. I have tried using the SWM power inverter and I also bought a BBC. Neither of them has worked. What am I missing? Any guidance would be appreciated by this novice. Thanks.
