WebJul 27, 2024 · Harmonics are that part of a signal whose frequencies are integral multiples of the system’s fundamental frequency. For example, with a 50Hz fundamental frequency, we can expect harmonics at 100Hz, 150Hz, 200Hz, and so on. Having defined it, we shall now see its relevance in electrical systems. 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.
