- | I built two antennas, one for 40m and one for 80m and I had access to a professional vector network analyzer. The length of the radiator was choosen arbitraryly, then the parameter N<sub>1</sub> was varied to find the right resonant frequency. After thatm the parameter N<sub>2</sub> was varied to get 50 Ohm. The resonant frequency is independend of the parameter. | + | I built two antennas, one for 40m and one for 80m and I had access to a professional vector network analyzer.
