Default Re: Wireless Self-Resonance Experiments

To get higher resonances on or near integer multiples of the fundamental you usually need some simple symmetry in the geometry (the simplest being a straight thin uniform length of wire). The further you depart from this the more the overtones depart from simple harmonics. What happens at the ends of the resonator also has an effect.
