Question: what is the electrical difference between rg-58 and rg-8 coaxial cable?
Answer: What electrical difference exists between the smaller RG-58 and larger RG-8 coaxial cables? These are probably the two most commonly used 50 ohm coax types; the RG-8 is thicker, less flexible, and as such has lower loss than the RG-58 coax. Just remember that as a general rule of thumb, a larger cable means less loss.
