##### VHF Band Very high frequency (VHF) is the [[ITU]] designation for the range of [[radio frequency]] [[electromagnetism|electromagnetic]] waves ([[Radio Wave|radio waves]]) from 30 to 300 megahertz (MHz), with corresponding [[Wavelength|wavelengths]] of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency ([[HF]]), and the next higher frequencies are known as ultra high frequency ([[UHF]]). [VHF radio waves propagate mainly by [[line-of-sight]] , so they are blocked by hills and mountains, although due to [[refraction]] they can travel somewhat beyond the visual [[horizon]] out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and [[FM]] radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. [[Air traffic control]] communications and air [[Navigation Systems]] (e.g. [[VOR]] and [[ILS]]) work at distances of 100 kilometres (62 mi) or more to aircraft at cruising [[altitude]].] >Covered in: >Mentioned in: >References: [[WP VHF|🌍]] >Required by: > >Related to:
