Half-Inch (1/2") corrugated coaxial cable is a heavy duty feeder cable designed for integration into large antenna systems. Half-Inch feeder cables are one of three main cable types used in passive Distributed Antenna Systems.
While designs can vary between manufacturers, half-inch cables always maintain a 15.87 mm outer diameter and use a 4.83 mm diameter inner conductor. This cable uses a solid corrugated copper outer conductor providing 110 dB of shielding effectiveness, and most importantly meets very low PIM targets.
