Abstract
The first structural aspect for mounting a telescopic antenna for an automobile includes a nut surrounding the top end portion of a spacer pipe and engaging with a threaded portion cut on the outside of the top end portion of a base pipe; a flange and a collar provided on a conducting pipe and the spacer pipe respectively and clamped between a contact portion provided on the nut and the top rim of the base pipe; and a flat ring positioned between the flange and the collar. The second structural aspect for mounting a telescopic antenna for an automobile includes resilient protrusions defined on the spacer pipe; holes defined on the conducting pipe, for engaging with the resilient protrusions when the spacer pipe is inserted in the conducting pipe so that the spacer pipe can be kept in position; and a portion around the resilient protrusions having an inside diameter greater than that of the spacer pipe. Both aspects help secure easy sliding of the antenna rods.
