Let me know if you succeed with the Wavefinder, I have a single dipole on my motorhome, connected to a Wavefinder, connected to a computer that was going begging, which is connected to the television (so you can just about see what you are doing) and connected to the aux. input of the Empeg. You couldn't do all that in a car and it doesn't work very well on the move, so I might as well have upgraded to a sattelite dish on the roof!
