For example, a 25-watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.

5 W will provide maximum achievable range in most conditions. That is because “maximum achievable range” is the horizon, which on average handheld-to-handheld is around 2 miles .24 Kas 2012
Read moreHOW FAR CAN 2 watts transmit?
So, a 2-watt walkie-talkie might broadcast within a range of 1.5 miles ; 3 watts = 2 miles; 4 watts = 2.5 miles; 5 watts = 3 miles; and so on. Actual distances may vary widely based on weather, UHF vs. VHF, etc. But these are good, general rules of thumb to go by when shopping for a new radio system.

So according to our rule-of-thumb, 2 people around 6 feet tall using a 5 watt handheld two-way radio, used on flat ground with no obstacles, will have a maximum range of approximately 6 miles .
Read moreHow is VHF range calculated?
To calculate VHF range, you may want to use this formula: VHF Range = 1.33 × (√H-aircraft + √H-gs) . Where: VHF Range in nautical miles, H-aircraft is the altitude of the aircraft in feet and H-gs is the height of the ground station antenna in feet.
