A communication system is disclosed that uses a received wireless signal combined with stored location data about the received signal to determine a location of the communication system or a component of the communication system. The communication system can include a receiver, a processor, and a memory. The processor is adapted to detect identification information in the received wireless signal, search the memory for identification data that matches the detected identification information, and retrieve location data associated with the matching identification information, thereby determining a general location or geographic region in which the receiver is located.

Method and apparatus for determining a geographic location

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.
