DIY Homebrew Linked End-Fed Half Wave (EFHW) Antenna With 64:1 Impedance Transformer (Unun) for 17M, 15M, 12M, and 10M
I am convinced that one of the major reasons that the higher frequency HF bands are relatively unused is because 17M and 12M bands are not resonant harmonics of the common 20M or 40M half-wavelength antennas that portable radio operators so routinely use in the field. I know some folks will decry “its the [prior] …
