I'm not aware of one Marty, but this might be a good 2 antenna option - a Larsen NMO150 5/8 wave base loaded antenna for 2 works very well on 6 as a base loaded 1/4 wave. That would leave you needing an antenna for 222, but would give you great performance on 6 and 2.
Comet makes a model CF-142 splitter/combiner that allows you to connect one antenna below 150 MHz and another above 200 MHz and use them on one rig. Available from your favorite ham store.
I love 6 FM, especially when the band opens for E-skip!
