The basic antenna formula will get you close 300000000/frequencey MHZ
and than do the metric to English conversion if needed. Otherwise, do
the 468 over frequency.

An antenna cut to frequency is just that, I would venture. So, HDTV is
more than likely a marketing strategy.
Simple is good; I would use a folded dipole, about forty inches on a
side, made of 300 ohm feed line, and fed with the same feedline. Simple
and inexpensive.
Good luck.
