Aluminum Outer coaxial transmission line
These aluminum outer/copper inner conductor rigid transmission line systems are available in 3-1/8", 4-1/16", and 6-1/8" (both 50 and 75 ohm) sizes. The elimination of the copper outer conductor reduces component prices and weight, decreasing the support component complexity, cost and installation effort. ERI's 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.
