text: The large VLF antennas used for high power transmitters usually have bandwidths of only 50 - 100 hertz, and when transmitting frequency shift keying (FSK), the usual mode, the resonant frequency of the antenna must sometimes be dynamically shifted with the modulation, between the two FSK frequencies.
