Frequencies Supported

Very High Frequency (VHF): 30-300 MHz

Very high frequency waves have linearity, yet they can go around obstacles to some extent. Since signals in the VHF band can carry more data than high frequency signals, they find wide application in television and FM radio broadcasting, as well as ship and aircraft communications, disaster prevention and administration radio, police and fire radios, ham radio, and so on.
