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.
