RF stands for radio frequency, the range of frequencies used to carry signals, onto which content such as television is modulated for transmission and later demodulated.
RF stands for radio frequency, referring to the frequencies used to carry signals through cable or space. Television signals, for example, are modulated onto an RF carrier and then demodulated by a television's tuner to recover the picture and sound. Equipment such as certain recorders and receivers includes modulators that place a signal on an RF channel for distribution to a television.
RF signals require cable and components designed to carry high frequencies with appropriate impedance and low loss. Coaxial cable is the standard medium for RF distribution, since its construction maintains consistent impedance and shields the signal from interference, preserving quality across the run.
In commercial and industrial communication and AV, RF distribution carries television and other signals throughout a facility. The coaxial cable and connectors handling RF must be matched to the frequencies and impedance involved to maintain clean signals.
Because RF signals require cable and components designed to carry high frequencies with appropriate impedance and low loss, coaxial cable is the standard medium for RF distribution, maintaining consistent impedance and shielding the signal from interference across the run.
Recognizing how RF distribution relies on coaxial cable helps illustrate why consistent impedance and shielding matter to preserving television and other high-frequency signals across a system.
At Windy City Wire, the focus on coaxial and signal cable for commercial communication connects directly to RF signal distribution. Supplying cable engineered for consistent impedance and low loss helps preserve RF signals across television and communication systems in commercial environments.
