I finally received my long awaited motorized fta system from satellite av. After locating Galaxy 25, my signal strength was 8o to 90. My quality was only 35 to 45. No amount of tweaking was able to raise it any. If the signal is near 90, is there any need to relocate the dish? The location is 35 north, 93 west. what can I do to increase th quality to a more desireable level?
