radio waves in the range of 30 to 300 MHz that are used in broadcasting TV signals
VHF, short for Very High Frequency, refers to a range of radio frequencies between 30 MHz and 300 MHz. These frequencies are commonly used for television broadcasts, FM radio, and some communication systems, such as air travel and sea-related radios. VHF signals can travel longer distances than UHF signals and are less affected by obstacles like buildings or trees. However, they have a lower capacity for data transmission. VHF is ideal for applications that require broad coverage, such as local radio and television stations, or communication in open areas like the ocean or the sky.
