Seawater Antenna Squirts Radio Signals

Naval tech researcher Spawar has figured out how to use a jet of seawater as an antenna. By squirting a measured length of saltwater through a “current-probe”, various antennae can be formed which will transmit and receive radio-waves on the UHF, VHF and HF frequencies.
Why bother? Ships have limited space for mounting antennae, and these [...]
