Frequency range spectrum
researchgate.net
- The primary distinction between these different spectrums is the frequency range spectrum. VHF frequencies operate between 30 MHz and 300 MHz and UHF Frequencies are between 300 MHz and 3GHz. In the UHF band, radio waves travel almost exclusively by line of sight (LOS) propagation and some ground propagation.

What are the differences between UHF and VHF? In general, VHF radios operate in the 138-174 MHz frequency band and UHF radios operate in the 400-512 MHz frequency band making UHF roughly three times higher in frequency than VHF. One important characteristic of radio waves is the wavelength which is the distance between peaks on a wave:

Frequency Range. One of the primary distinctions between UHF and VHF is their frequency range. VHF operates in the range of 30 MHz to 300 MHz, while UHF operates in the range of 300 MHz to 3 GHz. This means that UHF frequencies are higher than VHF frequencies.

Each band has advantages and disadvantages depending on the application. VHF, since it tends to bend with the curvature of the earth more than UHF, is ideal for outdoor applications where distance is the primary user need. However, a big disadvantage of VHF is that it does not work well indoors as it will not penetrate walls or reinforced concrete ...
Most public safety agencies in rural counties (Sheriff, Fire, EMS, etc) use VHF radios, especially in areas with low population density and hills and valleys. Surveyors, hikers, hunters, golf course personnel, farmers and anyone else primarily using their radios outside in rural areas would all be good candidates for VHF radios. Large construction ...
Another question that we often get is “Can UHF and VHF radios communicate with each other?”. The answer to this question is NO for most radios. There are some high-end public safety grade radios than can talk across both bands but they cost many thousands of dollars and are not a practical option for most radio users. Beware of cheap Chinese radios...

- The rule of thumb is... Typically, VHF for wide area vehicle two way radios with a repeater ; UHF for portable two way radios .
UHF operates between 403-470 megahertz (MHZ frequencies), offering a decent distance while working well inside buildings. The lower the frequency, the farther it can travel. VHF operates between 30-300 megahertz (MHZ). This has excellent distance on flat ground but works very poorly in buildings.
VHF frequencies range from 30 MHz to 300 MHz (though most professional two-way radios fall between 140 and 175 MHz). These frequencies have a much longer wavelength than UHF waves and are ideal for communication across wide, open spaces (think bodies of water, fields, hills, canyons, etc.).
