UHF or VHF...What's the Difference?


So, what is the major difference between UHF and VHF two-way radios? Most VHF business radios operate within 136-174 MHz, and UHF business radios operate within the 450-512 MHz range. This being said, we can see that VHF operates on a narrower spectrum and consists of less channels than UHF.

UHF stands for Ultra High Frequency and UHF radios can more easily penetrate through steel and concrete structures. Today, UHF radios are far more popular than VHF radios when looking at what different businesses are using for their daily operations. Because these radios can penetrate steel and concrete, most businesses like manufacturing plants, retail stores, and schools choose to use UHF radios within their building. UHF two-way radios typically have shorter antennas compared to VHF radios. One good tip for expanding coverage with your two-way radios is to add a longer whip antenna to your radio. In doing this, you may be able to avoid needing a higher powered radio at your facility.

VHF stands for Very High Frequency and VHF radios sit on the lower end of the spectrum. Because of this, it has longer wavelength which allows the signal to travel further. VHF radios are most commonly used in outdoor areas and open field operations. Aviation, Marine, and farming environments have all seen the benefits of using VHF two-way radios. Typically, these radios are not ideal for use in places like cities with high-rise buildings or indoor use. Depending on the type of radio being used, it is more likely that VHF will be cheaper compared to UHF.
