Check the listing for details. Dual Bifilar Tesla Coil module for radionics machine. Condition: New. Listed at 98.90 USD. A dual bifilar coil module based upon the design of Nikola Tesla's bifilar coil that cancels out the magnetic field and only emits the scalar waves. These coils have a dual winding which enables you to output almost twice the power compared to the first iteration of these coils! These modules are meant to be used in radionics healing devices. They can also be connected to our Scalar Wave Amplifier Modules that can accept signal sources via a 3.5mm audio connector cable directly from a PC (audio file, app, signal generator, etc.). Below you can find the suggested frequencies to be used with these coil modules. You can, however, experiment with other frequencies as well. The module can be connected to an external power or signal source via 4mm diameter banana connectors or via 3.5mm audio cable.
