Radia SmartFleece Earflap Hat Beanie EMF Protection, Anti-Radiation Cap, Brian Coat,Block Radiation, Black

Q: They say don't test it with a cell phone which makes no sense. If I can still get a cell phone signal of course that means it doesn't work right?

Thanks for the great question. There are 2 things to consider here: 1. Fabric - the shielding fabric is a custom yarn of silver. Our custom shielding fabric can block up to 59dB. To increase the shielding effectiveness beyond that we need to make the fabric thicker which is not suitable for wearable clothing purpose. For your information a very thick concrete wall with steel frames is only equivalent to approx. 35dB. Our shielding fabric provides protection much more than that. 2. Signal strength - in the past we can cut off 3G cell phone signal quite easily using our shielding fabric (we have been providing shielding solution for 5 years). As technology progresses we now have 4G and now 5G, we have found that cell phones now have signal strength much more than 60 dB this means the cell phone still gets the signal. See a video demo attached - a cell phone with 4G signal measures 1,800 mW/m2 drops to below 0.5 mW/m2 Hope this helps.

Q: don't the loose edges of this beanie let some emf in and then trap it in?

I doesn't fit an adult head, It is more of a children's sizing. I bought it for my 8-year-old son, and it is oversized, and fits his active lifestyle.

Q: Can you make a option with thicker shielding material id like the most protection i can get

The shielding effect of the fabric is so high that much more radiation comes from the opening of the beanie and by bending of the rather large wavelength waves at the edge of the beanie than through the fabric. More coverage of your head and body could enhance the shielding effect much more. You should try the hood and try to be in environments with lower level of radiation - for which acquiring a RF meter would be beneficial.

Q: Hello what is the shielding efficiency up to 5ghz? besides aesthetics how does it compare to your other beanie asin b09flszryp

We use the same shielding fabric for all our beanies. The shielding efficiency ranges from 18 to 70 dB, depending on the frequency. We have tested our fabric against the IEEE 299:2006. For your info, even at 10 dB SE that is equal to a 90% reduction of wireless energy.

Nützliche und bequeme Mütze

Das ist eine bequeme Mütze, die hilft vor Mobilfunkstrahlen zu schützen. Sie ist aus einem angenehmen und leichten Stoff genäht, sodass sie beim Tragen nicht stört oder einengt und durch die Form den Kopf gut bedeckt.
