Yes, Flam's 46.5m wire is only about 0.29 wl. However, making it
longer would raise the feedpoint Z even higher. There might be a
slight improvement in efficiency, but usually most of the extra
signal goes into higher angles (assuming the horizontal wire remains
at the same height, but is lengthened).
