This short study explores the effectiveness of altering the lengths and geometries of ferrite-core based antennas for the purposes of creating smaller andor lighter antennas with similar signal-to-noise ratios SNR. These antennas were primarily being used to record background atmospheric signals in the Very Low Frequency VLF range. Several width-to-length ratios are tested, as well as different styles of end pieces to help concentrate the flux in the ferrite cores. In the end, it is shown that long tapered ferrite cores can be used to save weight and space, if a small signal loss can be tolerated.
