What is the most common impedance of coaxial cables used in amateur radio?
8 ohms
50 ohms✓پاسخ درست
600 ohms
12 ohms
توضیح
Amateur transmitters, antennas and accessories are almost all designed around a 50-ohm system impedance, so 50-ohm coax such as RG-58, RG-8 and RG-213 is the standard feed line. 75-ohm cable exists but is far less common in amateur stations.
