Hope y'all can help me out. When we had our Directv installed at the house (Genie) we also purchased a separate reciever (D12 MP) and and a dish (20LNBR1-01) for the camper. The tech set the azimuth and all that for me, and told me all I had to do was hook it up point it the right direction and that was it. Problem is that I have tried to get this working several times to no avail. I do not know a lot about satellite tv. I asked the tech if my azimuth would change at the place we camp, only about 80 miles south of where we live, he said no. That said, I am getting no signal at all, absolutely zero. Are the rec. & dish compatible ? Do I need a power inserter? Should I have two cables from the rec. to the dish? Very frustrated, any help is much appreciated.
