Coaxial cables used for RF signal transmission are designated by which suffix?

The designation of coaxial cables used for RF (radio frequency) signal transmission is indicated by the suffix "RG." This stands for "Radiation Grade," a term historically used in military and commercial applications to denote the performance characteristics of these cables. Each RG designation, such as RG-6 or RG-58, corresponds to specific construction types, impedance levels (commonly 75 ohms or 50 ohms), and applications, making it easier for technicians and engineers to select the appropriate type of coaxial cable for their RF transmission needs.

Understanding this designation is crucial for ensuring the effectiveness and reliability of RF signal transmission, as different cables can significantly impact performance due to factors such as attenuation and bandwidth capacity.
