Thanks for the reminder about this -- I vaguely remember reading about 
their antennas years ago.  Question -- from the description, is the 
feedpoint higher than a quarter wave above ground?  A few years ago, I 
did an NEC modeling study of HF verticals that showed that doing that 
improved the vertical pattern and seemed to suggest that it reduced 
ground losses. Your thoughts?

The study is here.  http://k9yc.com/VerticalHeight.pdf
