Antennacraft VHF Antennas can be important if you are in an area where you still need a VHF channel; about 30% of USA broadcasters are still using one or more of *RF VHF channels 2-13. A VHF only antenna can fill in when you still need to get just those channels. Cut-to-band antennas are even more specific, with models for channels 2-6 or 7-13.
*RF is the real radio frequency that television stations broadcast on. These RF channels are used in selecting an antenna. The virtual .1 channel is the one you remember from the pre-digital transition, and is used to remember the "old" analog tv channel. To see your RF channels and virtual .1 channels, go to www.antennaweb.org. and input your zipcode.
