WebIt is the most efficient antenna design found so far for this frequency range, achieving efficiencies of 70-80% where other VLF antenna designs have efficiency of 15-30% due to the low radiation resistance of the very electrically shortmonopole.[8] Webbased mechanical antenna that does not require the change in the rotational speed of the permanently polarised material as in frequency modulation, hence overcoming the mechanical design challenges. A mechanical-based modulator is designed to control the attenuation of the radiation field in specific polarisation direction, and the signal
