My pacsat station (and backup/field day Oscar 10 station) consist of two 
quagis with both having 144 and 432 elements.  the elements are 90 degrees 
to each other

Nothing special here except in the "test" system that I built I got a lot 
better circularity and almost no interaction when I moved the 432 "start" 
point (ie the reflector quad) a little more then 19 inches aft of the 
reflector quad for 2 meters.  Otherwise they are built as "stock" from the 
QST article.

Been up over a decade through two moves with some maintenance but nothing 
serious.
