RCDD · Question #19
You must extend a video systems backbone coax cable that was recently installed. Which of the following coaxial cable types would provide the best performance for both analog and digital video?
The correct answer is B. Series 11. Series 11 is a large-diameter, hardline coaxial cable (approximately 1.125 inches outer diameter) designed for CATV/broadband trunk and backbone applications. Its large conductor size and low-loss dielectric give it significantly lower attenuation per unit length compared to…

Explanation
Series 11 is a large-diameter, hardline coaxial cable (approximately 1.125 inches outer diameter) designed for CATV/broadband trunk and backbone applications. Its large conductor size and low-loss dielectric give it significantly lower attenuation per unit length compared to smaller coax types, making it ideal for long backbone runs carrying both analog and digital video signals. RG-59 (D) and Series 6 / RG-6 (A) are smaller-diameter cables suited for shorter distribution or drop runs, not backbones. RG-16 (C) is a heavier-duty general-purpose coax but not optimized for CATV backbone use. RG-62 (E) is a 93-ohm cable used in legacy ARCnet and some specialized applications, not video distribution backbones.
