The estimates on the FCC site should be viewed as just that; estimates. The underlying model uses average terrain conditions between your antenna location and the station transmitter site. What really matters is the specific terrain that is actually between you and the transmitter but it would be unrealistic to include such in this general model. Also atmospheric conditions at any specific time play a role but the general model has to make an average type assumption.

And then it depends on the specific antenna situation that you have.

All of the above also applies to analog TV.

I am going to wait for the June 13th transition and then see what the story is at my specific location when all stations are on the final frequency assignments.

I don’t know if all DTV receivers are using the same chip set, probably not. Some may do a better job of compensating for the multipath resulting from signals reflecting off those hills that are between here and the transmitters. A lot of work has gone into developing adaptive equalizers for DTV receivers but I have not been able to find any brand specific test reviews. So I have yet to choose a brand/model DTV for the island.
