> I wonder what’s the science behind this. the same general reason why microwave band radio sees signal fade when there's rain on a point-to-point link through the air, but magnified greatly since the radio is now inside a solid mass of water. One of the problems faced by modern submarines for data communications, they use either ELF/VLF trailing antennas that are spooled out, while running 'kind of' shallow, or buoys, or antennas on periscope masts. |
