[Amps] 300 W single band mobile amp needed

[Tom Thompson]

I ran 100 watts from a bicycle.  I ran one of the RF exposure 
applications to check the exposure.  I think I was about 2 feet from the 
antenna and it was safe on 20 meters.  The motorcycle will probably be 
the antenna counterpoise so don't forget the rider is sitting on that.
