I have to respectfully disagree. There is a clear distinction between real and virtual channels.

Example - If you tell me that you would like to receive "WHTM, real channel 10", I know that that will require an antenna with high-band-VHF capability. It is also quite clear which signal on your TVFR is referenced, making it easy to be sure I am looking at the correct information for the signal you are interested in. Antenna selection is not influenced by the number of virtual channels carried in that real channel nor by the designation numbers of the virtual channels.

If you tell me you want to receive "channel 49" , there is the potential for ambiguity or confusion. Simply referring to "channel 49" leaves it to the reader to guess what you are referring to. If I were to find a real channel 49 (WGAL low in the red section on your TVFR) and a virtual channel 49.1 (WGCB real CH-30) listed, I'd not be able to understand what channel you were referring too.

If you spoke of "channel 49.1", I'd be confident you are referring to a virtual channel, but I'll need to look up the real channel number to know what type antenna is needed.


The majority of the channels available to you are not high-band-VHF (real channels 7 through 13). They are UHF (real channels 14 and up).

Cheers
