This circuit is a simplified adjustment of the 40, 80 and 160 m vertical antennas. For the required band, add the S1 conversion coil in the LC unit. The values ​​of C1 to C4 and the standard resistance R1 give the radiation resistance a range of 10 to 150 ohms. If the 500mW power supply can be used as a signal source, the meter can be 50uA to 200uA.
