the passage of the harmonic components. If the inverter is designed to provide power at a fixed frequency, a resonant filter can be used. For an adjustable frequency inverter, the filter must be tuned to a frequency that is above the...

feature of the antenna is that e.g. half a wave for 20m happens to be a full wave for 10m so the 20m half wave will be resonant as a full wave on 10m. Another trick to add a third band is to add a trap or high impedance coil at the end...
