I was getting over the air DTV before the fire wiped out my antenna. I had to use a signal booster because I am on the fringe of the coverage area about 90 miles from the tower. But, if I had my antenna pointed correctly I got tons of DTV channels and subchannels.
I was using an antenna similar to
this. You do not need a special "HDTV" antenna. If it can pick up UHF, it can pick up HDTV.
