What is the difference between RG59, RG6 and RG11?
The ‘RG’ acronyms have historically referred to ‘Radio Grade’ coaxial cabling, and today are referred to as ‘Series 59,’ ‘Series 6,’ and ‘Series 11.’ Each of these coaxial cables has a characteristic impedance of 75 ohms. Series 59 coaxial cable has a smaller diameter center conductor than Series 6 (RG6), resulting in higher attenuation (signal loss). Series 59 cables are typically specified for use as equipment patch cords because of their smaller bend radius and enhanced flexibility. Since Series 6 cables exhibit less attenuation than Series 59, they are more commonly used for distributed cabling and are recommended for use up to 90m (295 ft.). Series 11 cables support even less attenuation than Series 6 or Series 59 because the center conductor diameter is almost twice that of Series 59. Series 11 cables are recommended for lengths up to 112m (400ft.).
