VHF, in full very high frequency, conventionally defined portion of the electromagnetic spectrum including any radiation with a wavelength between 1 and 10 metres and a frequency between 300 and 30 megahertz. VHF signals are widely employed for television and radio transmissions.
Read moreHow far can a UHF radio transmit?
Since UHF transmission is limited by the visual horizon to 30–40 miles (48–64 km) and usually to shorter distances by local terrain, it allows the same frequency channels to be reused by other users in neighboring geographic areas (frequency reuse).
Read moreHow far can a 5 watt radio go?
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.
Read moreWhat is the range of VHF frequencies?
The VHF maritime mobile band consists of channels operating in the frequency range 156.000 MHz to 162.050 MHz , apart from those portions within this frequency range that are allocated to the land mobile service.

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 moreWhat range is VHF?
VHF includes radio waves from 30 MHz to 300 MHz . VHF waves must not exceed the local radio horizon of 100 miles.
