What frequency band is commonly used by VHF marine radios?

Marine VHF radios operate primarily in the frequency range of 156 to 162 MHz. This band is designated specifically for maritime communication, including ship-to-ship and ship-to-shore communications. The VHF marine band is crucial for safety at sea, as it is used for distress calls and coordinating rescue operations.

The frequencies within this range include well-known channels such as Channel 16, which is the international distress frequency. Additionally, this band allows for effective transmission over short to medium distances, which is ideal for marine communication where vessels are generally within sight of one another. The specified range also ensures minimal interference with other communication services and is standardized internationally, making it the go-to choice for VHF marine radios.

Other frequency bands mentioned in the options do not align with the recognized VHF marine radio ranges, making the choice of 156 to 162 MHz the only appropriate and correct answer.
