WebSometimes they work on second harmonics (i.e., 10m and 20m), especially dipoles. So your 60m antenna may work on 30m and 15m. If you have an antenna tuner (or one is built into the radio), you might be able to operate it all band, but you may have high SWR and common mode current in the feedline. WebThe harmonics are integer multiples of the input signal frequency, so will appear at higher points on the frequency dial. The harmonics may fall within the passband of your receiver, and are seen as valid signals even though they were generated in the receiver itself!
