[TechAssist] Re: HDTV outdoor antenna reception

As I understand HDTV broadcast, if I am viewing VHF channel 13, say, in 
normal mode I am watching channel 13 on a VHF carrier. But if channel 13 
is simul-broadcasting in HDTV, If I wish to see the channel 13 program 
in HD, and select the set to do so, the set automatically goes to a 
predetermined UHF frequency that chan. 13 uses to transmit HD. Is this 
correct? (as opposed to an additional VHF carrier piggybacking over the 
normal VHF info)
Correct?
Using channel 13 as my example, I thought if I had a good antenna 
capable of recieving a strong ch. 13 VHF signal, then I would also 
automatically get a good ch. 13 HDTV signal as well.
