The link is to the manufacturer of the antenna I use in upper northern Wisconsin. The model I have is DT-XFAMP20-1(0-80+ miles). It is mounted atop a 25' antenna tower. These antennas are pretty compact compared to the old massive analog antennas I've used.
Though the claim is that 80+ miles, due to elevation and trees I can't get broadcast signals from those towers that are ~78 miles out. I do get the channels through closer repeater towers. Those towers are ~30-45 miles away.
Link to some pretty good antennas.
