Re: Can this inform the 5G debate?
Not a radar tech., but spent ages on the lab bench designing microwave stuff, everywhere from C-Band to J-Band. Open waveguide? Of course. However, I have no daughters, but my 3 sons were conceived during that time, so that one doesn't hold water. Still got good eyesight, too.
As for a mere 200 mW peak setting off flash cubes - garn, don't believe it!
