Oh boy... JG Tiger asked me about this,
https://5grepeller.com/ So, here's what I've written back to him:
"I really have doubts about how that would work. You don't want to repel 5G microwave signal, you want to attenuate it, a.k.a. make it much weaker, so it could be useful, by not have you bathing in RF. Above 1GHz, just about anything does attenuate that,
windows, (Especially with tinted lead in it.), our aluminum-sided house, tree foliage, concrete, thick wood, etc. True, that these surfaces also bounce the signal, but every reflected signal will be attenuated to a degree. Now, are they trying to emit RF to cancel RF? That means, using a fire to fight a fire, which you don't want to be next to. Want to get away from intense 5G RF? Go into the deep woods, keep your windows rolled-up in the vehicle, go into a building, go underground in a cave, or go underwater. Attenuate RF, not some gizmo that claims to fight it. WTF?!?!? Don't believe the hype, but I'm open to what actual Field Strength Test Reports would show, if any. Demand that from that site!"
OK... So, let me be open enough to ask, is there anything to this, or a bunch of BS for the ignorant to suck-up? If anything, thought this to be a neat lesson to put out there. (Meaning, I did not post this here to bonk anyone, or to play on their intelligence, but to use the subject for an educational purpose.)
There, my C.Y.O.A...
