MHz is the symbol for megahertz, a unit of frequency equal to one million hertz, or one million cycles per second.
MHz is the standard symbol for megahertz, representing one million hertz, where a hertz is one cycle per second. The symbol appears throughout communication, video, and data specifications to express signal frequencies and the bandwidth of equipment and cable. Using the symbol keeps frequency values concise and unambiguous.
Because a cable's ability to carry a signal cleanly depends on its bandwidth, frequencies expressed in MHz are central to specifying coaxial and data cable. Cable rated to a particular bandwidth in MHz can support signals up to that frequency with acceptable loss, which directly affects its suitability for a given application.
In commercial and industrial systems, matching cable bandwidth to the frequencies a signal contains is essential to preserving quality. As frequencies climb into the MHz range and beyond, the construction of the cable becomes increasingly important to maintaining performance over distance.
Because a cable's bandwidth in megahertz sets a ceiling on the frequencies it can carry cleanly, the symbol MHz appears constantly in cable specifications, where it communicates capability at a glance to anyone selecting a product for a signal of a given frequency, from video and radio signals to high-speed data links across a facility.
At Windy City Wire, the focus on coaxial and data cable for commercial communication connects directly to frequencies expressed in MHz. Supplying cable with bandwidth matched to the application helps ensure that signals reach their destination with their quality preserved.
