Abstract
Abstract Aluminum-shielded coaxial cable is repaired by using a wraparound metallic sheet, such as copper, having a contact means on the sheet, such as "dragon skin" brass strips, and a sealing means, such as a mastic. The metallic sheet provides the electrical continuity and radio frequency shielding and the sealing means provides the environmental seal to prevent moisture from entering the opening in the aluminum shield. The sheet and contact means are held in position by compression means, such as clamps, and the sheet and compression means can then be covered with a wraparound heat-recoverable closure to protect the entire assembly.
