[Lowfer] Whip above the Top-Hat - Question Answered

[Andy - KU4XR]

Thanks to Pat -XSH/6 for the answer to my question. His reply
left me with no doubt:

> If you make an umbrella between the tip of a whip and the loading 
> arms then the entire assembly is considered the loading capacitance.
>
> At the end of a whip there is an open circuit (maximum Voltage and 
> almost zero Current). The plain whip (no loading) has an average 
> current in  much lower than the base current.
> If you accept that the current is what generates the "H" field which 
> is radiated, you want the maximum current all the way up the wire.
> The current getting all the way up the wire charges the capacitance 
> of the top hat to ground, not the capacitance of the little corona 
> ball to ground. Much more current can charge the larger capacitance.
> A whip above the loading arms will have very little effect, since it 
> has little current.

I hope this info will be useful to some else who may read it too.
Thanks Pat; and 73 to all ::
