When a coaxial cable connects the antenna to the transmitter, what property of the cable must match that of the antenna?

Question

Quizplus · Accepted Answer

The property that must match between the coaxial cable and the antenna is their impedance. Impedance is the measure of the opposition of the transmission of an electrical signal through a circuit. The impedance of the antenna and the coaxial cable must match to minimize signal loss and ensure maximum power transfer between the two devices. Choosing a coaxial cable with a different impedance than the antenna will cause signal reflections, loss of signal quality, and reduced efficiency.
