Navy engineers develop seawater antenna

U.S. Navy engineers at Space and Naval Warfare Systems Center Pacific in San Diego, Calif., have developed a system to use a stream of seawater as a radio antenna. Seawater is pumped through a magnetic probe to receive and transmit communication signals. The frequency and the bandwidth of the signal can be altered by adjusting the height and diameter of the stream.
