A system for transmitting a message, including an array of signal radiating elements for broadcasting signals that are unique one from another. One each of the unique signals is associated with one each of the radiating elements. One each of a set of transmitters is in electronic communication with one each of the radiating elements, and provides the associated unique signal to each of the radiating elements. A signal generating device receives the message from a message source and transforms the message into the unique signals. The unique signals, when broadcast, spatially interfere one with another such that the message is intelligibly receivable at only one location that is predetermined by the signal generating device, and is garbled at all other locations.
