Toroidal Ferrite Core Inductor Calculator

This calculator has been created by AC6LA and myself for the HF antenna designers dealing with antenna matching networks, symmetrizing transformers and common-mode current chokes. The ham radio antenna designers are the primary target group for this tool.

While the calculator may be of some use also in other RF design areas, the choice of the ferrite cores embedded in the calculator is especially suited for the applications mentioned above.
