If you do a Google search for Sterba curtain, the 
first hit you get is 
http://www.hamuniverse.com/sturba.html . While 
the antenna design for a slightly modified form 
of the array is fine, the patterns on 
http://www.hamuniverse.com/sturbamod.html result 
from a model with a phase reversal error in the 
feed system. The azimuth pattern on 10m (the 
design band) is significantly narrower than shown 
and does not have the huge high angle lobes. I 
sent the author corrected patterns two years ago, and he never posted them.
