What Does MUF Stand For?

MUF stands for Maximum Usable Frequency

MUF, or Maximum Usable Frequency, refers to the highest radio frequency that can be utilized for communication over a specific path during a given time period. It is critical in the fields of amateur radio and ionospheric communication, as it helps determine the optimal frequency for reliable signal transmission based on atmospheric conditions and the angle of incidence of radio waves on the ionosphere. Understanding MUF is essential for effective frequency planning and ensuring successful long-distance radio communications.
