Mitsubishi proposes to establish aerial repeaters from sea water
The construction of aerials is costly, cumbersome and extended process in time. Heavy iron farm are installed on the Foundation — all this requires extensive training and is not justified as a temporary solution. To escape from the process of construction of the antennas, in the company Mitsubishi Electric has proposed and tested in practice a very interesting method. As a transceiving antenna were used for the column of sea water. Salt water is a conductor for current. That, and the sea water around Japan rife.
Radio and TV can be deployed on the basis of the aerials of jets of seawater (Mitsubishi )
Mitsubishi developed the design of the repeater with the flow in the water jet of a high frequency signal. Also has a channel for receiving the signal from the water column. The development was named "Aerial Sea". Nozzle which discharges the pump is isolated, and a high-frequency current does not exceed the limits of the complex with the transmitter. Such a complex can be towed by boat to a specified point and deploy in minutes. For the system needs only seawater.
The overall scheme design and demonstration facility (Mitsubishi)
Mitsubishi proposed system has been tested as a relay terrestrial TV. In practice it was found that the efficiency of the antenna from the sea water is 70 %. About 30 % of power is lost due to the worst water conductivity, when compared with the conduction current in the metal. To compensate for the loss accounted for by increasing the transmitter power. However, it is acceptable losses when you consider that the antenna in its traditional form is no longer needed.
The company believes that this direction will be a good business. The only limitation will be that the technology is not suitable for high-frequency signal. Cellular and Wi-Fi pass. However, the length of the involved radio waves is determined by the configuration of the nozzle of the water pump. Perhaps the company will be able to think of something appropriate to relay high-frequency signal.
