Abstract
A telescoping antenna is disclosed having a plurality of telescoping hollow elements, including an inner-most hollow element. A button latches onto the top of the inner-most element. The inner-most element also includes a tab for preventing its full retraction into the other hollow elements. A wire antenna element is connected to the button, extends through the hollow elements, and is operably connected to a retracting mechanism. The button can be detached from the hollow elements in order to extend the wire antenna elements from out of the hollow elements. The wire antenna element is electrically connected to the receiver circuit such that the wire can act as a long-wire antenna of a calculable radio frequency (RF) resonance when extracted to a particular length.
