What is the electrical difference between RG-58 and RG-213 coaxial cable?

• A. RG-213 cable has less loss at a given frequency
• B. RG-58 is thicker than RG-213
• C. RG-213 is used for lower frequencies
• D. RG-58 is a higher quality cable

Answer: (A)

The correct answer highlights that RG-213 coaxial cable has less loss at a given frequency compared to RG-58. This characteristic is important for ham radio operators who want to maintain signal integrity over longer distances or in high-power applications. RG-213 has a larger diameter and thicker dielectric material, which contributes to its lower attenuation, or signal loss, over distance. This makes RG-213 a preferred choice for situations where fewer losses are critical, such as in repeaters or long antenna runs. While RG-58 is a more flexible and lighter cable, its higher attenuation makes it less effective for long-distance transmissions compared to RG-213. This difference in performance directly relates to the design and construction materials used in each type of coaxial cable, impacting their respective applications in ham radio and other communication systems.
