5G equipment can work on two different sets of wavelengths. UHF, which is heavily used by other things like cell phones, wifi, tvs, etc, and EHF, AKA millimeter wave, which is already used in airport security scanners, police radar guns, satellite communications, and some higher speed wi fi. So you're likely getting hit by that wavelength already, especially if you fly often.

Besides, I'd always heard that it was the extremely low frequency broadcasts that really mess with people. Stuff like HAARP.
