ClearCast HDTV indoor antenna -- overhyped?

[DavGoodlin]

Anyone who has bought an indoor antenna touted as "digital" will find one or two missing channels like Cleveland's WOIO 10 and WJW 8 (BTW we also have channels 8 & 10 in S. Central PA) Due to compromised design for VHF-Hi.

I have found that a custom-dimensioned home-made VHF yagi gets'er done!

Is this a general purpose Hi-Band Yagi (for 7 to 13), or is there some data missing from the table for adjustment of the element lengths/spacings for the individual channels listed?

Also puzzled by the term virtual used in the table, since the frequencies appear to correlate to real OTA channels.
