Very low resistive component in serie, equivalent to a very high
resistive component in parallel, eg 15.7 megohms in your simulation
of a perfect whip.

If you include the losses of a real whip in a real environment you
will get a result closer to the resistive component value that has
been suggested.
 
Hope this helps.
