Indeed, the ATSC exciter does have an adaptive equalization routine, but the sample point is taken at the output of the mask filter, not from a probe at the top of the tower sampling the output of the antenna. 




Thus at low VHF, that could be a big big problem if the antenna were
not certified by the manufacturer for DTV.  If I were a low DTV
station, I would test the signal with a non-resonant receive
antenna high in the air well away from the antenna (i.e. in the main lobe)
on a spectrum analyzer.
