I currently have an oval direct dish that gives me mediocre signal strength. I get low 70's , high 60's on both 101 and 109 birds. I am thinking about moving to Dish when I go high def but an worried about my signal strength? I am in the west coast so my dish pointing is very shallow...low trees can easily get in its way. Is Dish easier or harder to receive compared to Direct? I don't want to mess with new service if it is going to have poor reliability.
