Bookmark or Share- UHF vs VHF - Learn about radio frequencies - Radio DepotUHF (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.
- The Differences Between UHF and VHF Radio Frequencies - Midland RadioA 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
- VHF Propagation MapVHF Propagation Map This map shows real-time radio propagation from stations operated near 144 MHz. It uses data gathered by Automatic Packet Reporting System-Internet Service (APRS-IS) from packet stations in the amateur radio service. The map shows activity from the past hour.
- Viral hemorrhagic fevers (VHFs) | CDCLearn more about specific viral hemorrhagic fevers – their signs and symptoms, how they are spread, and how to prevent them. Diseases and Conditions information from the Centers for Disease Control and Prevention.
- Very high frequency - WikipediaVery high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).
