1-5/8-Inch (1-5/8") corrugated coaxial cable is a heavy duty feeder cable designed for large horizontal or vertical runs within major antenna systems. 1-5/8-Inch feeder cables, such as the popular CommScope AVA7-50 pictured, are commonly found within Distributed Antenna Systems (DAS), along with older UHF and cellular base stations.

While designs can vary between manufacturers, 1-5/8-inch cables always maintain a 51 mm outer jacket diameter and an 18.1 mm diameter inner conductor. This cable uses both corrugated copper inner and outer conductors providing low attenuation and 110 dB of shielding effectiveness. Due to its large diameters this RF cable type only supports frequencies up to 2700 MHz.
