What frequency range is used for Fleet Broadcast System communications?

The correct frequency range for Fleet Broadcast System communications is Low Frequency (LF). The Fleet Broadcast System operates primarily in the LF band, which typically ranges from 30 kHz to 300 kHz. This frequency range is chosen because LF can provide long-range communication capabilities, which are essential for maritime operations. The atmospheric conditions that affect LF signals, such as the ability to follow the curvature of the Earth, allow for more effective communication over vast distances compared to higher frequency bands.

LF is particularly advantageous for communication in maritime environments where ships may be far from shore and need reliable contact with fleet command and other units. This is crucial for maintaining situational awareness and coordinated operations. In contrast, other options such as Medium Frequency (MF) and High Frequency (HF) do not have the same operational range or effectiveness for the specific requirements of the Fleet Broadcast System.
