The CB radio frequencies are distributed in a range of 27 MHz. At these frequencies, you there are different channels (only 40) with different purposes, that are open or closed. Signaling requires a specific area. The frequency is the range of waves in which the signal passes.Basics of Radio Waves - dummiesf = c / and = c / f. The higher the frequency, the shorter the wavelength, and vice versa. Radio waves oscillate at frequencies between the upper end of human hearing at about 20 kilohertz, or kHz (kilo is the metric abbreviation meaning 1,000), on up to 1,000 gigahertz, or GHz (giga is the metric abbreviation meaning 1 billion).They have corresponding wavelengths from hundreds of meters radio frequency
