This monopole at 14 mHz would be 1/4 wave. As the description notes there is no loading coil as the radiator is self resonant at the frequency of operation although the info indicates a reactive component.
It’s interesting to see the plot shows a nearly perfect omnidirectional pattern with the offset radial system. Would this be a result of the 1/4 wave radiator or is that not a factor? A plot for our typical base loaded 3 meter antenna with offset radials would be very informative.
Articles I’ve read typically relate to a skewed pattern when the radials are not symetrically placed around the base of the antenna.
