I can get it here from around 285 and Hampden. But only on my old VHF/UHF antenna that was cut for channel 2 and up. My high VHF/uhf, the Winegard
HD7698P (a big ass , high gain high VHF and UHF antenna) up about 45 feet can't lock on at all using the Quatro 4k. I am only about 12 miles from Lookout Mountain and can see the towers from my roof. With the old 6 element maybe 4 foot long antenna up about 20 feet I get 65% Signal level and about 70% signal quality. Symbol can be 90 to 100%.
Which means that unless you have a decent antenna tuned for low VHF, you likely will not be able to get a useable signal at any distance much further away.
It is indeed several channels of nothing I care to watch
HOPR a loop of promos for the HOPPER device
STDIO some clips from concerts etc. May be full concerts, but it has not yet been good enough for me to watch for any length of time.
ONPPV promos of their pay per view content. NOT full movies (at least that I have seen)
AUD1 through AUD3. music from DISH network. Nothing I have found that I like.
I believe they are using these for testing ATSC3. Probably as an adjunct to their DISH service at some point. They are constantly screwing around with things.
They seem to be intermittent, and pretty crappy PQ/SQ overall, even in the best case.
If you never get any of them, I don't think you are missing anything significant. In any case, unless you are close and have a GOOD
LOW VHF antenna, forget it.
