Splet31. jul. 2024 · Low frequency is in the range of 30 kHz to 300 kHz. One of the important properties of LF signals is that they will get reflected by the earth’s ionosphere and thus it is suitable for long-distance communication. Since it’s a long wavelength and less attenuation from big terrains like mountains, it is generally called ground waves. Spletヘクトメートル波.
