	Very high frequency ('''VHF''') is the range of radio waves from 30 to 300 megahertz (MHz). Frequencies immediately below VHF are denoted high frequency ([[HF]]), and the next higher frequencies are known as ultra high frequency ([[UHF]]).		Very high frequency ('''VHF''') is the range of radio waves from 30 to 300 megahertz (MHz). 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). There are three ham radio bands in the VHF range: 6 meters (50 MHz - 54 MHz), 2 meters (144 MHz - 148 MHz), and 1.25 meters (222 MHz - 225 MHz, plus 219 MHz - 220 MHz for fixed digital message forwarding systems only). 2 meters is the most widely used VHF band, at least in the Brookings area.
