A critical difference between these two frequencies is that UHF (ultra high frequency) may not travel as far as VHF (very high frequency), but it provides more bandwidth occupation. In the U.S., the FCC oversees operating frequencies and defines them in four categories. Low-band VHF: 49-108 MHz; High-band VHF: 169-216 MHz; Low-band UHF: 450-806 MHz

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: Wavelength is inversely proportional to the frequency. Wha...
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...

Jul 14, 2024 · 4. Licensing and Frequency Regulation: Both UHF and VHF frequencies are regulated by national and international bodies, and in many cases, users need licenses to operate. The availability of frequencies might also influence your choice, as some bands might be more congested or heavily used in certain areas. 5. Equipment Cost:

vhf radio frequencies. When it comes to VHF radio frequencies, there are a few things you need to take into consideration. The most important factor is the range of the transmission. VHF radios typically have a longer range than UHF radios, making them ideal for communications over longer distances.
Jul 17, 2023 · What are UHF and VHF? UHF, short for “Ultra High Frequency,” and VHF, short for “Very High Frequency,” are two types of radio frequencies. The UHF low band goes from 378 to 512 Megahertz (MHz) and the high band from 764 to 870 MHz. On the other hand, VHF’s low band ranges from 49 to 108 MHz, and its high band from 169 to 216 MHz.

May 2, 2014 · In some areas of the United States, it is a challenge to get a new license for VHF frequency, especially for Public Safety, this is because there is only so much radio bandwidth and many of VHF frequencies are already in use by other organizations. UHF (Ultra High Frequency) Is typically in the 400MHz to 520MHz range of frequencies.
