I'm glad to see this thread too.
I'm no expert on any of this HDTV stuff, but it's been my observation that the Samsung TS360 is not as good as other receivers for picking up OTA broadcasts. Maybe that is the problem for a few of the other posters in this thread too.
I originally had a Sony SAT-HD300 HDTV receiver, and I was able to get all the digital stations no problem with a pair of rabbit ears on top of my set. But that receiver had a malfunction trying to get HDTV satellite signals, so DirecTV sent me the Samsung TS360 to replace it with which fixed my satellite problem, but it seems real finicky with OTA signals.
The TS360 couldn't lock onto some of the stations with rabbit ears, so I now put a Channel Master 4221 4-Bay antenna in the attic and locked onto 10 stations, but it still drops out of Fox 10, WB 61, and channel 5 on occasion. The weird part about channel 5, is that I got it strong all week without a problem, but when the HD football game was played on Sunday it would constantly lose the signal. Then after the game when normal SD was broadcast on channel 5, it picked it up no problem the rest of the day.
Is an HD signal somehow harder for a receiver to lock on and pick up compared to a regular SD signal? I wouldn't think so, but I can't figure out why channel 5 has been fine all week and all day today except during the HD football game when it constantly lost the signal and made it unwatchable. The weather didn't seem any different to me.
The signal strength meter on the TS360 is pretty much useless too compared to the Sony SAT-HD300 receiver, as the TS360 bounces around all over the place. So it's hard to tell what's going on there.
I live in Chandler near Alma School & Elliot, about 12 miles from all the towers. You'd think since most of the towers are in the same spot on top of a mountain, and close by, that we wouldn't have any trouble getting signals over the air. But I'm having grief with this TS360 that I wasn't with my Sony. I don't really want to spend money on a better receiver at the moment either to try to pick up OTA signals. I also wonder if we have some kind of interference in the area? Because I would think we should be able to pick up stations no problem with all the towers so close and on top of the mountain.
I was curious if anyone knew if we in the Phoenix area will eventually be able to get CBS HD and NBC HD over the satellite any time soon? It's offered in other markets, but for some reason it's not currently offered in the Phoenix market.
