What is the electrical difference between RG-58 and RG-213 coaxial cable?
There is no significant difference between the two types
RG-58 cable has two shields
RG-213 cable has less loss at a given frequency✓Richtige Antwort
RG-58 cable can handle higher power levels
Erklärung
RG-213 is a much larger cable than RG-58, with a thicker centre conductor and more dielectric, so it has lower resistive loss at any given frequency and handles more power. Both types are commonly 50 ohms, so the difference is loss and power handling, not impedance.
