To simplify the construction of a telescopic antenna which is projected and retracted, respectively, by a flexible wire, a rotatable wind-up drum (10) is formed with an inner space (17) to provide for wind-up of the flexible wire, the inner space, likewise, retaining a gear ring (20) in which gear projections (41) of the wire are engaged. The wire, preferably, is an elastic plastic wire element, coupled to the projecting telescoping element (A2) of a telescoping antenna (A), the drum (10) being driven by a motor (35) which receives rotation coupled thereto by a worm drive (29-34).
