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).
