75 ohm rca connector.
Posted by Duster on March 10, 2017 at 20:57:48:
The issue of a 75 ohm characteristic impedance coaxial cable is valid, while the notion of a 75 ohm impedance matched rca connector is a misnomer. The proper function of an rca connector when used for a 75 ohm termination is to preserve the hopefully precision 75 ohm characteristic impedance geometry of a coaxial cable dielectric when terminated with any given rca connector. The most vital aspect is simply not to crush the foamed/cellular/solid dielectric (insulation) between the center conductor and the braided shield, which will do well to keep the 75 ohm characteristic impedance of the coaxial cable unaffected from end-to-end.
