Many O&Os kept their VHF assignment when they switched to digital to 
maintain their local DMA 'identity' like 7ABC, NYC and 6ABC in 
Philadelphia. Some had operated on those channels since the dawn of 
television, just after WWII.

Some digital viewers had to install huge outdoor antennas to receive 
those Lo-V stations. The ten element 'bird perch' above my roof measures 
7 X 16 feet! This is for WPVI, 6ABC in Phildelphia, 39 miles distant.

Heres an FCC list of all DTV station assignment with both their old and 
new RF channel assignments.
