I lost my line of sight to the Western arc satellites due to trees in a neighbors yard. I had read that all the new installs in my area are on the Eastern arc and A friend of mine had an Eastern arc dish he let me have. I was able to set it up and get a signal. Every morning I have to unplug the cables from the check switch and plug them back in to reacquire the signal. I found that it fails during the overnight update. My receivers are compatible with the EA satellites. I'm not sure if the arc you are on is listed on your account. Do I have to tell Dish I am now on the Eastern arc?
