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.

With digital, is not the exciter designed to compensate for any
amplitude AND PHASE anomalies of the transmit antenna? This is
a few lines of computer code and some canned FFT routines, even
in the absolute worst cases. In good cases it could be
a simple FIR filter code. Does eat up DSP power, of course.
