I have a SuperDish 121. I'm using Dish Receivers 301, 6000, & 510. I believe I've already pointed the dish at the position with the strongest possible signal. I did so by adjusting the dish to point to the position that gives me the best signal from 121 (since signal transmitted from 121 is much weaker than 110 & 119). 6000 is the only receiver that requires DishPro Adapter. It is also the one that seems to get the best signal over-all. I am not sure if the adapter might have helped boosting the signal that went into the 6000 receiver. With 510 & 301, the signal sometimes is lost for certain channels (most of channels from 121, some from 110, and few from 119), such as channels 684, 506, etc. I've tested with a shorter RG-6 line directly connected from SuperDish to my 510 reciever. It does not seem to make any difference. Questions: 1. If there a way to improve signal further? Keep in mind that I think the position of the dish is already optimal (I used a sat. signal meter to find best spot for Sat 121). 2. I uses DP34 switch. Does the order of connection position to the LNB's matter? 3. Will a powered signal booster help? Is there specific kind I need to get? 4. I remember at one point, I used to get much better and more stable signals from the satellites. At some point, thing got worse. Is there any change with the satellites, or perhaps it's some config change I might have done? Thanks for any help/advise you might be able to provide.
