It was a partial switch from VHF to UHF. Prior to the transition channels 2 through 6 were in the VHF low band. After transition these all moved to UHF with the associated increased path loss of UHF. Most retained the same channel number, like 6-1 out of Portland which is now in the UHF band.

Channels 7 through 13 were in the VHF high band and still are. So we get channel 8-1, just barely, on a high gain high gain Yagi antenna designed for only VHF high band.

Most "digital tv" antennas sold today are UHF antennas of various designs that have only a token gain in the VHF high band. Thus shortchanging channels 7 through 13.
