You are aware that many of the DTV signal are UHF band? Right?


This:
"Are DTV signals broadcast on special frequencies?

No. DTV broadcasts use exactly the same channels as regular analog
television. While many DTV stations are now occupying UHF broadcast
channels, broadcasters are allowed to move back to their original VHF or
UHF TV channel once the transition to DTV is complete.

The only caveat is that TV channels 51 through 69 will be auctioned off
for other uses at the end of the transition to digital TV. Stations who
originally had analog channels in this band will have to move, no matter
what.

One potential problem with re-using low VHF (2-6) TV channels for DTV is
the possibility of interference from other signals during certain times
of the year. "Skip" may bring in distant broadcasts on the same channel
and create interference. Impulse noise is also a problem on low VHF
channels. What’s more, the physical size of low VHF and high VHF
antennas is much larger than that of a UHF antenna.

Tests so far seem to indicate that high VHF channels (7-13) are quite
well suited for DTV broadcasts, and many broadcasters plan to move back
to their high VHF channels at the end of the transition. VHF
transmitters also cost much less money to operate than UHF transmitters."
