This contribution analyzes the sensitivity of a future linear collider for weakly coupled gauge bosons and briefly discusses how, in case of discovery, its properties can be determined with high precision.4 pp., to appear in the proceedings of the International Conference on Linear Colliders (LCWS 04), Paris, France (April 19-23, 2004)High Energy Physics - Phenomenologytext
