Corona discharge around Lakhovsky antennas of a Multiwave Oscillator

What is corona in a Multiwave Oscillator?

Some users of the Multiwave Oscillator (MWO) or Tesla coils report seeing a blue glow around the Lakhovsky antennas. This phenomenon is called corona discharge. It occurs when the voltage becomes so high that the air around the antennas ionizes. Although it looks impressive, it is often a sign of energy loss and not proof that the resonance field is stronger or working better.

Why corona is not a positive sign

Corona discharge can make an MWO appear spectacular, but technically speaking, it is actually a sign that the system is out of balance:

  • Energy loss: voltage leaks into the air instead of contributing to the resonance field.

  • Resonance disruption: ionization changes the capacity of the antenna and makes the field less stable.

  • Uncontrolled field lines: instead of a harmonic distribution, random discharges occur.

  • Material stress: antennas wear out faster due to ozone, heat, and oxidation.

Such a visible corona is therefore not a sign of a “better”
