Abstract
A lossy transmission line in which the effective length of the line is reduced by providing resistive ferrite beads spaced along the line to provide constant power loss per unit length. Inductance ferrite beads may be included equally spaced along the line. Resistive beads are located with increasing frequency per unit length from the beginning of the line until a maximum bead density per unit length is achieved. The lossy line is suitable as a terminating unit for a portable travelling wave antenna and in other situations where size reduction is desirable.
