The Alderman and Grant design of the slotted tube resonator has been modified with a different lumped capacitor distribution to obviate the need for a balanced electrical feed at low frequencies (6 MHz). A saddle coil resonator and a strip line resonator have been tuned with similar lumped capacitor distributions to obtain electrically balanced resonance.
