[Elecraft] Two and three element Yagi design data

[Charles Greene]

Hi,

I am redoing a two element moxon square wire beam we used for field day by 
making it a bit wider and adding a three element wire 20 meter beam 
inside.  The PVC tubes we used (18' at each end) are too heavy and bend too 
much, so we are going to replace them with 21' fiberglass tubes.  Can 
someone please refer me to some design data for two element and three 
element beams.  EZNEC 3.0 works pretty good, but it's easier if  you have a 
starting point.  From RI, a 60 deg beam covers 95% of the US, so we don't 
need to rotate it.
