Hey dont give up yet, try pulling up, or pushing down on the dish when you are on a weaker channel,see if you can get any improvement in picture quality. Preferably, one on either end of the arc (that you're getting channels on) If you can tell which way the dish needs adjusting by doing that, maybe we can help you find the proper adjustment to your motor, bracket, or pole. The pole the dish is on has be as vertical/plumb as you can get it for the motor to track properly.
