VHF (Very high frequency) is the ITU term for the range of radiofrequency electromagnetic waves (radio waves) that are from 30 to 300 megahertz (MHz). Today’s VHF’s are not the same as those of 20 years ago. Today the VHF is competent in sending digital messages or calling specific stations into your radio (Digital Selective Calling - DSC).
