Hi, i just recently had dish pro 500 installed. I'm trying to get the best possible signals from both sats. I've learned that the local channels such as 3 6 and 10 on sat 110 is high say 100 but when u go up to say 200 cnn on 119 the signal is low say 87 and the higher i go the lower the signals get 69. what do i need to know about getting both sats at or above 100. The settings for my zipcode are good. by rotating the scew i'm able to increase one sat signal but in doing so decrease the signal of the second sat. right now i have found a compromising setting for both sats but i'm not satified. right after i had my system installed my parents had theres installed with much higher signals from both sats and theres is even shooting through trees. any suggestions?
