What frequency band do marine VHF radios operate within?

Marine VHF radios operate within the frequency band of 156-162 MHz. This range is specifically allocated for marine communications to ensure reliable communication between vessels, as well as between vessels and shore stations. The VHF frequency range is crucial for safety and navigational purposes, allowing for effective communication in emergencies, weather updates, and routine maritime exchanges.

The chosen frequency band minimizes interference from other types of radio communications, which is essential in a busy marine environment. This range also allows for clear line-of-sight communication, as VHF signals can travel further over water compared to other frequencies, particularly due to the curvature of the earth and the lack of significant obstacles.

Understanding this allocation helpsensure that users operate their equipment within the designated frequencies, maintaining regulations and contributing to safe boating practices.
