A signal transmission tube may be made by disposing a reactive polymeric material within a confinement tube and leaving a portion of the tube interior unoccupied. The tube may be formed by disposing a layer of paint comprising the reactive polymeric material on the interior surface of the confinement tube, extruding the confinement tube over an elongate rod that comprises the reactive polymeric material. The rod preferably has a high surface area configuration, e.g., the rod may comprise a longitudinal bore therethrough or may be star-shaped, cross-shape...
What is claimed is: 1. A method for making a signal transmission tube, the method comprising extruding over an elongate rod a confinement tube having an inner wall defining an interior of the confinement tube, the rod being comprised of a solid reactive polymeric material having reactive pendant groups chemically bonded to the polymer backbone and being configured to provide a continuous, longitudinally extending unoccupied portion of the interior of the confinement tube.
