No,  I didn't miss that. read my post again.

With reference to another post, I wish to add that antenna Q has nothing to 
do with the current in the wire. The current is computed from ohm's law that 
states I= sq rt of P/R.  Thus a halfwave long dipole with an impedance of 50 
ohms and 100 watts fed to it has a current of 1.414 amps regardless of the 
Q. The curent can not be greater than that otherwise we would be radiating 
more power than is fed to it. Q only affects bandwidth. Incidentally, the 
current can be increased by making the wire shorter. The impedance will be 
lower, and, with the same 100 watts fed to it the current will be greater 
than 1.414 amps. Will this make the short antenna a better antenna because 
it has more current? No.
