7/8-Inch (7/8") corrugated coaxial cable is a heavy duty feeder cable designed for lengthy runs within large antenna systems. 7/8-Inch jumper cables are commonly found within Distributed Antenna Systems (DAS), along with older UHF and cellular base stations.

While designs can vary between manufacturers, 7/8-inch cables always maintain a 27.5 mm outer diameter and a 9 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.
