What is the VHF frequency band?
Radio frequency range from 30 MHz to 299 MHz. The sub-bands most commonly used by fire are: VHF-FM Lo band: Frequency Modulation 30 MHz - 80 MHz, of which fire frequencies are between 30 MHz and 50 MHz.
What is VHF and UHF frequency range?
In the United States, the frequencies used for these systems may be grouped into four general bands or ranges: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz). VHF represents “Very High Frequency” while UHF represents “Ultra High Frequency.”
What band is better VHF or UHF?
VHF has smaller frequencies which means interference with other radios is common. UHF, on the other hand, is an all-around better signal for long distance communication. UHF is better when using radios for indoor use like buildings or around cities.
What are high VHF channels?
VHF signals cover 2 frequency bands. The Low-VHF band covers channels 2-6 and the High-VHF band covers channels 7-13. Because these signal wavelengths are longer than UHF signals, they can more easily bend over and around certain obstructions in the terrain between the TV broadcast tower and the receiving TV antenna.
