Radio refers to the use of electromagnetic waves, generally between about 10 kHz and 3 GHz, and in particular their transmission through space for communication.
Radio is a general term, used principally as an adjective, for the use of electromagnetic waves roughly between 10 kHz and 3 GHz, and in particular for transmitting signals through space. These radio frequency waves carry information wirelessly across distances, forming the basis of broadcast, communication, and many wireless systems. The term spans a broad range of frequencies and applications.
Although radio transmission travels through space, the equipment that generates, distributes, and receives radio signals relies on cable to carry those signals within and between systems. Coaxial and signal cable connect antennas, transmitters, and receivers, and their impedance and loss characteristics must suit the radio frequencies involved to preserve signal quality.
In commercial and industrial communication, radio frequency systems support broadcast, wireless, and signal distribution. The cable feeding radio equipment is selected to match the frequencies in use, maintaining signal strength across the connections within a system.
Because radio equipment relies on cable to carry signals within and between systems even though transmission travels through space, coaxial and signal cable connect antennas, transmitters, and receivers, with impedance and loss characteristics matched to the radio frequencies in use.
Recognizing how cable carries radio signals between antennas, transmitters, and receivers helps illustrate why impedance and loss matter to preserving signal quality across a radio frequency system.
At Windy City Wire, the focus on coaxial and signal cable for commercial communication connects to the radio frequency systems that move signals through space and through cable. Supplying cable matched to the frequencies involved helps preserve signal integrity in broadcast and communication applications.
