The invented system includes a beacon affixed to the object subject to loss and a tracker held by the owner of the lost object, the tracker repeatedly, electronically 'interrogating' the beacon with a radio frequency (RF) signal, the beacon repeatedly responding to the interrogation, and the tracker effectively triangulating to determine the lost object's nominal location by a measure of distance and direction. In accordance with one embodiment of the invention, the tracker includes one or more antenna each coupled with a power amplifier to determine in real time the distance and direction of the beacon from the tracker. In this embodiment, the tracker indicates both distance and direction of the object-affixed beacon to the tracker-holding owner via a simple color-coded light array. In one embodiment of the invention, the invented antenna of which there is one (or more) includes a helically wound conductor of elliptical cross section disposed around the hollow interior surface of a hollow mandrel.
