I have an H21 that i just bought and it is working just fine when set up on my home SWM system. However when I set it up outside at the tailgate w my extra 18 in dual LNB dish and set it up as such, I cannot get any signal when aimed in the right direction. I even bought the dishpointer app for my iphone and still can't get anything. All zeros on the 101 sattelite. Is the LNB busted, did I set something up wrong? Please help! Thanks.
