Howdy! Tom,   
      
   According to the website TVFOOL.COM the Over The Air Digital TV Channel   
   21.1 is a Virtual frequency, and is Transmitted on the Real Channel 8 .   
      
   I was thinking Channel 21 was UHF until I read that the other day.   
      
   Channel 8 is VHF as far as my thinking processes goes from what I read   
   about TV Channels in books that I have here.   
      
   Channel 8 is between 180-186 Megacycles,   
   Channel 21 is (was?) between 512-518 Megacycles,   
   according to a book printed in 1959.   
      
   That seem to me to mean I would need a VHF TV Antenna instead of UHF.   
      
   Is that how You think also?   
   Thanks es 73
