Bands of frequencies, especially in the VHF and UHF parts of the spectrum, are allocated for communication between fixed base stations and land mobile vehicle-mounted or portable transceivers. In the United States these services are informally known as business band radio.
Aug 15, 2020 · UHF (Ultra High Frequency) and VHF (Very High Frequency) two-way radios each have their advantages and disadvantages. We will discuss these advantages and disadvantages in the sections that follow so that you can choose the correct frequency band for your application.
Feb 22, 2018 · This chart shows the relative positions of the most common frequency bands, and is not to scale. ELF = Extremely Low Frequency . VF = Voice Frequency . VLF = Very Low Frequency . LF = Low Frequency . MF = Medium Frequency . HF = High Frequency . VHF = Very High Frequency . UHF = Ultra High Frequency . SHF = Super High Frequency . EHF ...

This Online Table of Frequency Allocations may display amendments that have been adopted by the FCC but that have not yet taken effect.
Apr 24, 2021 · 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.
HF (High Frequency), UHF (Ultra High Frequency), and VHF (Very High Frequency) communication bands have distinct characteristics and are utilised for different purposes based on their propagation properties, frequency range, and applications.
VHF is Very High Frequencies while UHF is Ultra High Frequencies. VHF is a frequencies used mainly outdoors and travel further. UHF is for indoor use where interference is low.
Jul 19, 2022 · Wavelengths within the VHF and UHF range are particularly accessible to ham radio enthusiasts, but what are the differences between UHF VS VHF? With lower frequencies, and longer wavelengths, VHF is more suited for outdoor communications over longer distances though requires larger antennas.
United States Frequency Allocation Chart. A printed version of the most recent version of the United States Frequency Allocations: The Radio Spectrum Chart (published in January 2016 from data as of September 2015) is available from the U. S. Government Publishing Office at a cost of $6.00 per copy.
The VHF/UHF bands are also home to a wide range of systems, including repeaters, gateways and satellites. Innovative digital developments are also key to our ability to access new spectrum at 71 and 147 MHz (See VHF Spectrum Release) .
