Abstract : Disclosed is a low profile wideband VHF antenna wherein impedance matching over the required operating band is provided without the use of multiple circuit components, for tuning, switched into and out of the antenna by an assembly of switch contacts. The antenna is comprised of an end and preferably a bottom fed vertical radiating rod or monopole element whose upper end is terminated in a substantially flat circular top capacitance disc via a frequency sensitive inductance constructed of a ferrite core inductor whose micron characteristic varies approximately inversely with respect to frequency.
