Bandpass filters, ferrite chokes at antenna feedpoints, stubs on power 
amp outputs to suppress even order harmonics. k9yc.com/7QP.pdf show a 
setup we use three times a year for FD, 7QP, and CQP every year.

There are dozens of super-stations around the world built for 
contesting, where legal limit stations simultaneously light up every 
band that's open. And I'd guess that a third or more of SERIOUS 
contesters are running SO2R. The biggest stations run (at least) two 
radios on each band, one "running" (calling CQ) and the other in S&P 
mode (tuning up and down the band for multiplers).

http://k9yc.com/Multi-Station.pdf provides an overview of all of the 
mechanisms that can couple RF between stations.
