But not to channel 2. They are after VHF high-band channels (Ch7 to
Ch13 172-212 MHz) vacated by by stations moving to UHF. The high-band
channels have vastly better building penetration than low band, and the
antennas are smaller. Practically no one wants the problematic
propagation and E-skip interference potential of low-band VHF any
more. Except perhaps some LPTV (low power community stations)
scavenging the leftovers of the spectrum, that shouldn't be any problem
to 6 meter hams.
[Have you noticed the new-generation "all-channel" TV antennas from
Channel Master and Winegard? They cover VHF-HI and UHF, but not low
band. The longest element at the rear of the log-periodic array is about
ONE-HALF (if they cover FM) to ONE-THIRD the length as on "classic"
all-channel ants that had to get down to 54-60 MHz for chan 2.]
