A slide tube is coupled to the lower portion such that the elongated radiating element is movable with respect to the slide tube. A compressible contact is provided on a bottom portion of the lower portion. The compressible contact is compressed by an inner sidewall of the slide tube at least when the elongated radiating element is in the extended position to facilitate maintaining the elongated radiating element in the extended position and provide an electrical connection between the elongated radiating member and the slide tube.
