Medium Frequency (MF) refers to a range of radio frequencies between 300 kHz and 3 MHz. This frequency band is commonly used for AM radio broadcasting, maritime communication, and some aviation services. MF signals can travel long distances, especially at night, due to the reflection of radio waves off the ionosphere. In the context of radio communication, AM radio stations typically operate within the MF range, allowing them to reach a wide audience. The characteristics of MF signals enable them to penetrate urban environments and provide reliable communication over various terrains, making them essential for both entertainment and information dissemination.
