No, but in general, more is better, and it's better if it's not laying 
on the ground.  It simply becomes the other half of the antenna that 
you're loading -- think of it as providing a return for the current.  
When someone said "you want a ground on the KX3," what he SHOULD have 
said is that you need some sort of return for the antenna current.  
Radials are one form of return, a counterpoise is another.  A 
counterpoise is simply another conductor connected to the chassis of the 
antenna tuner (or transmitter).
