3/8-Inch (3/8") corrugated coaxial cable is a medium duty jumper cable designed for short interconnections within large antenna systems. 3/8-Inch jumper cables are one of three main cable types used in Distributed Antenna Systems.

While designs can vary between manufacturers, 3/8-inch cables always maintain a 11.2 mm outer diameter and use a 3.3 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.
