I've read a few posts about the "eastern arc"; apparently this is a different set of sats to aim dishes at on the east coast? I have dishHD asbolute and lose 129 in light rain or clouds. On a clear day, such as right now, my 129 signal varies from 26-32. From what I gather, the "eastern arc" provides better signal strength; yes? Can my dish be repointed for this purpose? My dish says "Dish 1000" on the front, and has a DPP triple LNB.
