Very high frequency designates the portion of the radio spectrum from 30 MHz to 300 MHz. These wavelengths travel strictly by line of sight and penetrate light foliage or non-metallic building materials better than higher frequencies. Broadcasters use VHF for FM radio and legacy television, while aviation and marine operators rely on it for local two-way communications.
