Excitation of a long wire antenna - antennas from 200 MHz to 1 Hz

Measurement results are presented for using magnetic feeders (toroid ferrite rings) to excite antennas with lengths: 0.3, 0.6,13,3,20,25,30,35,40,45,50m. The applications of using ferrite ring feeders are discussed that cover the frequency band from 200 MHz to 1 Hz range.
