There is an easy way to work linear birds from mobile. All you need is a 
single band SSB mobile radio (FT-857, FT-897, etc), a portable SSB receiver 
(TH-F6, etc.) and very simple antennas for the downlink (like the CJU for 
mode J, 1/4 whip for mode B, etc):

I´ve made hundred of QSOs via FO-29 using this little station. It also works 
nice on FM birds.
