In a cell RF system, the main transmission line is called what?

• A. Coaxial Cable
• B. Feedline
• C. Hardline
• D. Ribbon Cable

Answer: (C)

The main idea is that the line carrying RF power from the base station to the antenna is called hardline. It’s a rigid, high-power feeder designed to minimize signal loss over long runs and to withstand outdoor, tower-side conditions. That combination of low loss and rugged construction is what sets hardline apart from flexible coax used for shorter or lower-power runs. Ribbon cable isn’t used for RF transmission in this context, and while “feedline” is a broad term for any line to the antenna, the specific term for the main high-power path in cell sites is hardline.
