What is the maximum power output for a marine VHF radio?

The maximum power output for a marine VHF radio is 25 watts. This is the standard output for most marine VHF radios, which are designed to ensure effective communication over considerable distances while also adhering to regulations set forth by maritime authorities.

Marine VHF radios using 25 watts power are able to maintain reliable communication across a range of approximately 20 to 30 nautical miles, depending on factors such as antenna height, terrain, and atmospheric conditions. This combination of power and range makes it suitable for both commercial and recreational vessels operating in coastal waters and beyond.

Lower power options, such as 5 watts or 10 watts, may be used for certain types of communications or by handheld VHF radios, but they do not provide the same range and reliability as the 25-watt output. Higher power outputs, such as 50 watts, are not standard for VHF radios as they are typically not necessary for the intended maritime applications and may not comply with regulations.
