[Amps] MOSFET amp filtering - was: auto-tune

[Tom Thompson]

Jim,

/Lousy soil does NOT vary the vertical angle, it simply attenuates the 
signal.  In the near field, it burns transmitter power by warming the 
worms. In the far field, it degrades ground wave and weakens the first 
reflection that creates the vertical pattern./

Lousy ground does raise the take off angle of the maximum point on the 
lobe of a vertical.  EZNEC shows the maximum point on the take off lobe 
going from 18 degrees with very good ground to 26 degrees for rocky 
mountain ground.
