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
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.
