"... an antennas lowest VSWR freq and the antennas resonance freq may not be the same"

And to add just a tiny bit more to that... there are very few times when any antenna's input impedance is ever 50 ohms, or even 'close'. If it is, and if some kind of impedance matching device isn't used, then hang onto that thing 'cuz' it's a miracle!
