I have seen in some places recommendations for .6 wavelength spacing for lower sidelobes, however I have also read that each type of antenna and height needs to be modeled to arrive at optimum spacing.

Hello Todd,

You are going to a lot of trouble and expense to properly stack a pair 
of antennas far apart that are very poor to begin with.  I suggest you 
simplify your life considerably and increase the gain of your system by 
simply putting up something like a single M2 6M7JHV yagi.  Sorry, but 
life is too short to see you struggle along the wrong path....  GL and 
VY 73, Lance
