Mitsubishi Electric Develops an Antenna using Seawater Plume

Mitsubishi Electric has developed an innovative antenna system, called SeaAerial, that shoots a column of seawater into the air to create a conductive plume for the transmission and reception of radio-frequency waves.

The system, which is thought to be the first seawater antenna, is capable of receiving digital terrestrial broadcasts for normal viewing. The company said it is investigating conductive and transmutative liquids as new materials for antennas.
