I'm a new-comer and am looking for help with a new 5 LNB dish set-up for Directtv. I have it on the house and it is plum, I took down a 3 LNB that I had installed sucessfully, and now I have the cables and new LNB installed with satellite and am unable with a course beginning to get any signal. I set the azmuth, tilt and evelation as directed. Checked the mast for plum, and have tryed an hd20 and a regular box for signal. I'm setting the receveiver for the 110a satellite and looking at add #'s. Please help if you know something that I'm missing. Oh Yes! I called Direct tv and they did'nt know what I was talking about. I must say that if Directv didn't have such a good product, when it is working of course, they would be in serious trouble.
