The only significant pattern or directivity change with 1/4 wave spacing of 
any antennas is end-fire. Broadside will have little advantage, unless it is 
to null one side (in which case it is actually an endfire-endfire 
combination).

This means the base cells have to be somewhat in line with the direction or 
directions you want to null or peak.
