I live in an area where it will be a very cold day in Hell before our Local stations begin to broadcast in HD, But sometimes we work in a town that's about 50 mi. outside Sacramento, their Analog reception is Pretty good, but I've heard rumors that HD doesn't travel as far as the Analog signals do.
It's hard to sell people a system if you're not sure that they'll get what they want.
How far have you guys gotten Off Air HD receivers to work? ( I don't care for the theoretical B.S. I want real world.)
P.S. It's pretty flat around here

Speaking from my personal experience, I live approximately 62 miles outside of Houston and I receive all of our local hdtv signals perfectly----of course, I have a 75' antennae also, so this probably helps a bit; I can even pick up a couple of distant channels from surrounding cities that are 80 plus miles away--just not as crisp.

Yes, just not very well; grainy; however, the stations at 50-60 miles are near perfect.

I always thought with digital signals, either you get it or you don't. True there may be some freezing, pixelization/blocking and dropouts with a borderline low signal, but I've never seen an HD signal that was "grainy". From what you describe, to me, it sounds like an analog signal.

Just my interpetation,

Dave

Our outer limit for reliable reception seems to be 50 miles out over variable terrain. Beyond that, we get reception in some locations and not others, some days not others, some stations not others, you get the picture. Antenna choice is crititcal for both close in locations <15 miles, and far ones >40 miles. The Rf amplifier you choose also has a large impact. I only use the DTC100, the rest have been too much trouble to deal with. There is a great forum for this over at avsforums.com. My advice, pull RG11 where you can, signal loss is your enemy, even a few db can make the difference. Have more than one antenna on hand. Make your Channel Master distributor your friend. Carry a variable Rf attenuator. BTW, at 50 miles, the analog picture is there, but unwatchable, the digital is pristine.
