I feel there is a need for submarines to communicate effectively with other submarines ships and airplanes. The same invention can also be used for trapped miners to communicate with their rescuers. If for a moment we oversimplify it, the invention is basically a radio transmitting and receiving antenna system that works under water as well as above it and attaches to standard radio transmitting and receiving equipment. Its purpose is primarily that submarines can communicate with other submarines, even robot submarines, ships, as well as aircraft flying overhead or even land based stations. Whether the submarine is submerged or surfaced should make no difference in transmission or reception of radio signals except for a slight difference in the tuning o f the transmitting system. The system also works underground up to a point depending on the distance and radio frequency used. This is basically in a nutshell what it's all about. Unlike other systems in use at present, which work on sound which is plagued by echoes, or the electrical conductivity of water that limits its use to water only, o r in some cases in one way transmission only, my system has no such obstacles and even can be used for TV transmission.
