VHF transmission range is a function of transmitter power, receiver sensitivity, and distance to the horizon, since VHF signals propagate under normal conditions as a near line-of-sight phenomenon.
VHF consists of radio waves from 30 to 300 MHz and is used in some critical communication systems, like FM Radio, marine communications, long-range data transmission, and two-way land mobile radio systems.
VHF, conventionally defined portion of the electromagnetic spectrum including any radiation with a wavelength between 1 and 10 metres and a frequency between 300 and 30 megahertz. VHF signals are widely employed for television and radio transmissions.
VHF band radio waves operate on lower frequencies but are longer, so they work better for long-range outdoor use in job sites, campgrounds, and farms. Unlike UHF waves, VHF cannot penetrate objects like buildings or other large obstructions.
What VHF radio is, how it works, and why it's essential for marine, aviation, and emergency communication. Learn about VHF frequency ranges, types, licensing.
VHF represents “Very High Frequency” while UHF represents “Ultra High Frequency.” The FCC also determines who can operate in each band and who has priority if more than one user is operating.
