Stacked Lindenblads?



Hi All,

Has anyone tried stacking Lindenblads for LEO use?  I've got in mind a 
"Christmas tree" of 4 antennas ( RHCP & LHCP, 70cm & 2m).  Between each 
pair of antennas is a preamp & rf relay for switching polarity.  I figure 
as long as there's enough separation (>1/2 wavelength?) between the 
antennas, there shouldn't be a problem.

Thoughts? Comments? Gotchas?

Thanks!
