Homebrew DIY AM ferrite antenna, variable capacitor configuration
The higher in frequency you go the less turns you need on the ferrite. To cover a wide range you would wind the ferrite to resonate at the higher frequencies with minimal capacitance then use a variable 0-365-pf capacitor for tuning then switch in fixed capacitors to lower the tuning range of the ferrite.

A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.
