There is no "distance" index in radio communication, because the ultra short wave communication is line of sight transmission, and the signal is blocked and interfered by buildings, hills, forests, electromagnetic fields, etc.,  ...

The best two-way radio systems for yachts help keep everyone safe while enabling clear and consistent communication across the ship, and all the way back on land. Many things can go wrong out at sea, from ice blocking the designated route to rough currents that threaten to capsize a boat. If anything goes wrong, the ability to communicate is key to getting assistance in a timely manner. Hence, why two-way radios are a staple necessity onboard yachts, or any other type of vessel.  ...

Over the years, handheld VHFs have become both a good deal more reliable and, in many cases, a good deal more sophisticated than in years past. This has resulted in a wide range of models that vary dramatically in terms of size, performance, and features. Still, one of the first things you need to think about when choosing a particular model remains how long the radio will continue to function on a single charge, something that is largely a function of battery size.   ...

Radio travels as waves… similar to light, and like light, it can be reflected, reduced, or even stopped by other objects. A popular answer is 'line of sight’ which essentially means 'if you can see it, you can talk to it'. This is generally a good guide. You must remember that the radio signal comes from the radio aerial (not the radio itself) and therefore mounting the antenna higher allows the radio to 'see' further.  ...

The antenna is an important component to marine radios and if there’s an issue with the antenna there’s going to be an issue with your coverage and range. Check to make sure the radio’s antenna is not bent, cracked, or otherwise broken to the point that the metal coiled antenna piece is exposed. In addition, make sure the antenna is screwed on correctly to the antenna connector of the radio.  ...

Communication. It’s essential.  You wouldn’t take a long car ride without your cell phone and you shouldn’t be without a VHF radio when out on the water.
