I have had the Dish 811 since it came out in December 2003. I too have a silver sensor in the attic with an in line signal booster attached. I can get KALB all the time, PBS if I re-orient the antenna, KLFY (56) occasionally. I have never gotten KLAX, but until they go high power on their main tower, I don't think I have much of a chance. I don't really like the sat HD from dish that much, they seem to compress the channels a lot, especially ESPN. HDNet is the only one that does not compress because of contractual agreement with DISH. I have never gotten an OTA dolby audio signal except on one of the PBS sub-channels(not the DH feed), only regular prologic 2 channel. Most of the DISH HD channels are in Dolby Digital. The OTA PBS signal seems to be compressed, as I get a lot of pixelation with fast moving images. I don't know how much of what I see is due to the 811 DISH receiver, but when Cox comes out with HD, I may switch. They said last year that it would be available in the 1st quarter of this year, but looks like that's not going to happen. There is just not enough HD programming out there.
