Topband: Ground rods

[Bruce A. Clark]

  Not true. Maybe you are thinking of Dipoles, Yagi etc. 
  Try an  BOG antenna with an isolated transformer  with the ground 
side of the antenna winding connected to a  1 foot ground rod and 
check signals, then connect it to a long ground rod and see the 
difference. 
  Or take the ground off the transformer completely,  and see how much 
signal with only one side of the 150 ohm winding connected. 
   
  Recommend long ground rods, as they are  more  consistent from band 
to band than a very few short receiving radials. 
   
  The KB-1 BOG antenna transformer typically has 3-4 pf inter-winding 
capacity. Not enough coupling, to the coax shield, to have much 
transformer  grounding/radial affect.
