Well, I only read the first few pages of this thread, but I'll throw in my two cents. Forgive me if this was covered...
Regarding antennas- I am absolutely in agreement. Every Dish owner should have a GOOD rooftop antenna if at all possible.
BUT- they don't help if there are no signals to get! I have a $100 10 foot antenna 15 feet in the air just to get ONE analog station. (I pick up a couple others, but I don't watch spanish or religious.) That station's digital signal currently isn't strong enough where I live- they are operating at low-power. Even if I could get it, it doesn't broadcast anything in HD, so what's the point?
I agree HD LIL is a waste of bandwidth, but it's the only way around the stumbling blocks set up by the affiliates, lawmakers, and satellite providers.
DirecTV has taken at least one positive step- offering distant HD feeds for all four major networks to at least some people. Dish only offers CBS for some reason...I don't qualify (not that I ever watch CBS anyway). If I had DirecTV, I would only qualify for Fox. But there is NO OTA HD here. It's not a matter of putting up the right antenna. It just doesn't exist.
I should be able to get a Network HD feed for every network- a low wattage UHF analog translator 25 miles a way should not count as a local HD feed. The network feed should not be a distant channel- it should just be a network feed. Only my timezone- no time shifting. At the end of primetime, the feed goes black until late-night starts.
If the affiliate wants me to watch, they should have to provide me with a proper OTA HD signal. Theoretically, my local NBC affiliate will some day go full power and HD- when that happens, turn off my feed.
Oddly, neither DISH nor DirecTV ( nor the government) have any problem feeding me an NBC channel from Phoenix, even though there IS a local Flagstaff NBC affiliate I can recieve in Analog SD.
DISH could provide 3 timezone feeds for each network that broadcasts in HD. That's 21 channels. Broadcast ONLY programs in HD- otherwise it goes black. THAT'S an effecent use of bandwidth. But the affiliates and will never allow it. Until the lawmakers grow a set and allow this, HD-LIL is the only way.
