resonance frequency

On single turn loop the resonance frequency is determined by its circumference, which is half the wavelength.

I dont understand why the resonance frequency isnt depending on the inductivity and the capacity, i thought the resonance frequency is calculated by the formula:  [Image: 4649ce6f1aa676a20ef8e19ba16d4b25.png] 


I have another question: In section 4.2.2. (amplifier 13) is said that specific VLF-signals have to be filtered out, but the VLF-signal is a electromagnetical signal so it should affect magnetical antennas too. Still the amplifier for magnetical antennas only uses 1 filter for frequencies above 50kHz and doesnt offer a filter for frequencies above 49k and 22k. Why the signals only need to be filtered out when a electrical antenna is used? (Or is this just not implemented yet?)
