Comment on NanoVNA vs. Loop antenna SWR testing [Question]
einfach_orangensaft@sh.itjust.works 3 days agoAh yeah sad, southern germany is a bit far away (besides maybe during high solar activity but even they the skips may fly just right over). Thx for doing some calculations, on the safety distance aspect of it, i kinda assume the psychological effect (knowing that u in the RF near field) is probably bigger an the real effect of 4W of RF heating…and i probably just hallucinated the slight metallic taste in my mouth after 1min of keying down while tx testing (my brain do be like that sometimes).

Most likely :)
Keep in mind, I assumed worst case, both with my estimate and with what I’ve input into the program. Plus, the legal limits probably have some rather large safety margin.
To be honest, below 10W and without a highly directive antenna, you’re probably fine.
Again, I am not a doctor, most RF limits assume mostly the heating effect is relevant. I personally don’t believe it causes you brain cancer or makes you want to drink coca-cola. But I might be wrong.
