What is the normal amount of signal fluctuation? I am running a DP301, using an extra large dish to compensate for my edge of the footprint location. Signal strength is satisfactory. But it fluctuates a fair amount. On windy days, it will fluctuate 5 or 6 points as I watch it. But even on perfectly calm days it will fluctuate 2 or 3 points. In all cases I am talking about fluctuation during the few minutes that I am watching the meter. Are these fluctuations normal, or should I hunt for an offending tree limb?
