SSC Pacific has developed a technology that uses the magnetic induction properties of sodium chloride (salt) in seawater to transmit and receive communication signals. The device works by pumping a stream of seawater through a current probe.
The height of the seawater stream determines the antenna’s frequency. For example, UHF frequencies require a 2-foot high stream of water, while VHF and HF frequencies require 6-foot and 80-foot high streams (respectively). The width of the stream determines the antenna’s bandwidth.
The antenna requires a relatively small footprint and can be modified to accommodate multiple frequencies and bandwidths by stacking current probes and adding additional spray nozzles. The technology could be used on land with salt-supplemented water, replacing large unsightly antenna towers with fountains.
The device could also be used on land or sea as a solar- or battery-powered emergency antenna system.
