I just got an Ariza 700 and tried to connect to my dish and the signal stregnth on it shows 80% or more, even when the dish is not facing the sky, I can put it down on the ground it will still show 80%. This is not normal or is it? I'm using a RG6 dish cable, even when I don't connect the cable to the LNB, I get over 80% signal. Can anyone suggest something?
