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.
