They transmit and receive on the VLF band or Very Low Frequency. Check on the Web for information on places like Jim Creek Naval Radio Station. They have huge water-cooled vacuum tube transmitters and a antenna array hanging on a canyon.
under water they use very low frequency wave.
above water communications is done with high freqency waves.
the difference is because of the transmission medium.
under water the water molecules can not oscillate as fast as air molecules above water. its very complicated.
waves generated inside water
either using their regular antenna. or on greater depth most subs can float a radio bouy.
