What is a characteristic of RHF communications?

A characteristic of RHF (Radio HF or High Frequency) communications is that it operates in the high frequency range, typically between 3 MHz and 30 MHz. This frequency range allows for long-distance communication, as high frequency waves can reflect off the ionosphere, enabling signals to travel beyond the horizon. This is particularly advantageous for naval operations where communication over long distances is essential.

RHF communications are widely used in maritime environments because they can effectively penetrate oceanic conditions and reach distant ships or coastal stations. The ability of high frequency signals to travel long distances makes RHF reliable for communications in situations where other methods might fail, such as during adverse weather or in remote locations.

Understanding the operational range and the significance of high frequency is crucial for effective communication planning and execution within naval operations.
