- Why not use radar underwater? The catch is that radar uses radio waves in the microwave frequency range, or approximately one centimeter in wavelength. This wavelength range is used because it is easier to direct the waves with small antennas in narrow beams. Unfortunately, Microwaves are strongly absorbed by sea water within feet of their transmission. This renders radar unusable underwater.
Radar is microwave.
....there's a lot of scientists with serious doubts about 5G....180 of them.
When industry and government are in unison, it worries me..

there you go again...appeal to authority.
and no...I'm not going to down load pdf file.
not from one of THOSE sites.
wow...a whole 180?
that might make a small department at motorola.
I know a guy who worked there..we have dinner together fairly often.
...180 is more willing to put their names down , than the re was in the 'anti global climate change' forum a decade or so ago...just sayin...
