Difference Between RG-58 and RG-213 Coaxial Cable

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

There is no significant difference between the two types

This is incorrect; while both cables serve similar purposes, they have distinct characteristics that affect their performance.

RG-58 cable has two shields

This is incorrect; RG-58 cable typically has a single shield, and the main difference lies in the loss characteristics and physical construction.

RG-213 cable has less loss at a given frequency

This is correct; RG-213 cable is designed to have less loss at a given frequency, making it more efficient for certain applications.

RG-58 cable can handle higher power levels

This is incorrect; RG-58 cable typically handles less power compared to RG-213, which can handle higher power levels.

Explanation

When working with amateur radio systems, the choice of coaxial cable is crucial due to its impact on signal quality and performance. Coaxial cables are used to transmit radio frequency (RF) signals from the transmitter to the antenna. RG-58 and RG-213 are two commonly used types of coaxial cables, each with different characteristics that make them suitable for various applications. The key electrical difference between RG-58 and RG-213 coaxial cable lies in their loss characteristics at a given frequency. Specifically, RG-213 cable has less signal loss compared to RG-58, making it more efficient for longer cable runs or higher frequency applications.
