How is the characteristic impedance of Series-59 coaxial cable defined?

The characteristic impedance of Series-59 coaxial cable is defined as 75 ohms. This specification is crucial for applications, particularly in video and broadband communications, where optimal performance in terms of signal reflection and power transmission is necessary. The 75-ohm impedance is designed to match the typical load impedance of video equipment and broadcast systems, ensuring minimal signal loss and distortion.

In professional use, such as in broadcast environments, this impedance allows for the effective handling of high-frequency signals, critical for maintaining signal integrity over longer distances. Using cables with the correct impedance ensures that the cable system operates efficiently within the specified frequency range, facilitating clear transmission and reception of video information.
