Very high frequency waves, also called VHF waves, are electromagnetic waves in the frequency band from 30 megahertz (30 million cycles per second) to 300 megahertz (300 million cycles per second). VHF wavelengths range from 1 to 10 meters. The Federal Communications Commission has assigned portions of the VHF band to television and frequency modulation (FM) radio stations and to amateur radio operators. Frequencies assigned to TV are from 54 to 72, 76 to 88, and 174 to 216 megahertz. Frequencies assigned to FM are from 88 to 108 megahertz. VHF waves travel in straight lines, like light waves. Their transmission is ordinarily limited to line-of-sight paths. Obstructions, such as buildings, reflect or absorb them.
