One problem is that you are supposed to scan the receive antenna
vertically from 1-4 meters and use the maximum amplitude at each
frequency.
Also, it's not clear to me how you are going to get vertical and
horizontal polarity - are you proposing two separate orientations of
the antennas? If so, that is what the ANSI std. calls for.
