Jack, W6FB, made a good point about resonant antennas. Going with  this 
idea, separate resonant antennas should be used for each band, and mobile  
antennas, being high-Q may be particularly desirable. However, minus separate  
bandpass filters (to augment interference rejection), physical separation of 
the  antennas by some(?) distance is also desirable. In the case of 
horizontal  antennas (dipoles, yagis, etc), orientation (right angles or end-to-end) 
along  with physical separation is key.
 
Multiband and non-resonant antennas can't be counted on for signal  
rejection in most cases.
 
The best lessons for minimizing station-to-station interference can  be 
gleaned from multi-multi stations; their challenges and how they overcome  them 
are always insightful.
