Very high frequency, abbreviated VHF, is a band of the radio spectrum spanning 30 to 300 MHz.
Very high frequency, abbreviated VHF, is the band of the radio spectrum from 30 to 300 MHz. These frequencies have wavelengths of a few meters and propagate mainly by line of sight, which makes the band well suited to FM radio broadcasting, television, two-way land mobile radio, and aviation and marine communication. Very high frequency sits between the high frequency and ultra high frequency ranges.
Operating at very high frequencies places requirements on the cable carrying the signals, since loss and impedance matching become important as frequency rises. Coaxial cable used in the VHF range is engineered for appropriate loss and consistent impedance to preserve signal quality.
In commercial and industrial communication, band designations like very high frequency guide the selection of cable and equipment matched to the frequency. Recognizing the band helps in choosing cable suited to its requirements.
Because loss and impedance matching become important as frequency rises, coaxial cable used in the VHF range is engineered for appropriate loss and consistent impedance to preserve signal quality, with band designations guiding the selection of cable and equipment matched to the frequency.
At Windy City Wire, the focus on coaxial and signal cable for commercial communication spans the range of frequencies a facility may use, including very high frequency. Understanding the band supports the selection of cable engineered for the consistent impedance and appropriate loss that these signals require.
