I am trying to install a dish (direct tv) at my cottage in the woods. Lots of trees. I had it running 2 yrs ago with a signal 60s-80 ish and it worked most of the time. Now I cant get a signal 2 yrs later. Trees taller? Bad LNB? (do they go bad?) bad aim? Im trying to find out what sat. I'm shooting for from zip13679. It was 101 but Im wondering if that changed in the last 2 yrs. I didnt use it last year. I used the sat pointer tool here and it shows alot of direct tv sats from that zip. How do i know which one Im aiming for? Thanks
