ERI now offers complete aluminum outer/copper inner conductor rigid transmission line systems in 3-1/8 inch 50 Ohm. Not only does the elimination of the copper outer conductor reduce component prices, but the reduced weight decreases the support component complexity, cost, and effort required to install the transmission line system.
ERI's field proven bellows expansion compensator accommodates the differential expansion between the inner and outer conductor and vertical and horizontal spring hangers are designed to support the system and compensate for differential expansion between the tower and vertical and horizontal runs. The systems also include galvanic adapters to allow interconnection to new or existing brass and copper components.
