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.]
