I was at my college football tailgate this weekend and had trouble getting the 110 bird. I was able to get 101 at 97% but could only get 0% on 110 for the HD channels. I tried different coax connections but I can only assume it was a fine tuning issue. I setup the tilt and elevation according to the receiver (H21) by inputting the zip. BTW, I was working with a slimline dish. Any suggestions?
