[Amps] CB amp directly coupled via cap to antenna

[TexasRF at aol.com]

We all know there HAS to be some kind of matching to get significant power  
transfer. It could be this simple:
 
The rf choke could be sized to provide the needed inductance for an L  
match. The series coupling C can be sized to transform the plate load Z to 50  
ohms.
 
That actually would be the lowest loss matching scheme and therefore  
deliver the most watts to the antenna.
 
Q?  We don't need no stinking Q!  Actually the output C of the  tube and 
coupling C would force some Q to be present. Maybe just enough?
