I never said it did.

What you say here and some others have addressed is the current 
distribution on the antenna's element (I'm do not disagree with that 
analysis) , but you and the others have failed to address the antenna 
*system's* current  path. This means the complete path of the current to 
and from the generator (transmitter). In other words the loop current.

And a dipole is a Hertz.
