I put up a fairly large antenna when we lived 60 miles from the transmitters and pulled in 30 some channels from Phoenix and Tucson stations. We moved to about 12 miles from the transmitters and pull in 70 channels with just a small antenna on the back wall of the house.
Whenever we are where there is cable, we go around 150 - 200 channels and can't find anything that we want to watch, so we certainly wouldn't pay money to have that kind of TV. We don't like the over abundance of re-runs and old black and white movies that are on cable.
We receive the pure digital signals broadcast by the stations, not signals that have been compressed and then expanded like cable or satelite.
