Basic wavelength λ (meters) = 300 / f (MHz)(or more precisely 299.792 / f for exact c, but 300 is fine for HF/VHF)All linear dimensions of a Moxon (or almost any antenna) scale with wavelength. 2. Resonance scalingWhen an antenna resonates at a measured frequency f_measured but you want it at f_target:scaling_factor = f_measured / f_targetNew dimension = old dimension × scaling_factorExample: first build resonated at 140 MHz, target 146 MHz → factor = 140/146 ≈ 0.9589 → shrink everythi
