Update: DTV Reception Beyond 35 Miles

Two weeks ago I reported on the Centris study questioning whether DTV could be received more than 35 miles from a transmitter site. I asked for readers’ comments on their DTV reception to see if their experience matched the results of the Centris study, which used the CEA Web site antennaweb.org to predict DTV coverage using small- and medium-sized antennas.

The response was overwhelming. Several readers provided detailed information on the antennas they used as well as the distances to stations they commonly received. With very few exceptions, the reports indicated DTV reception beyond 35 miles was not difficult, although it did require the right antenna. And in some cases interference was a problem.

I’m still compiling the results and will have the details in next week’s RF Report.
