What Should You Know

Does the signalproof apparel blocks 5G network?

The answer is: YES, it does. 

5G or 5th generation of mobile network uses multiple low and high frequencies, for instance 700 MHz or 3500 MHz. It mostly runs on 700 MHz which was used by terrestrial TV in the past and emitted from long distances with very low intensity. Now it comes directly in cities and highly multiplies its intensity. The penetration of 700 MHz into buildings is very good and actually the best amongst all active mobile network frequencies, that’s why it’s going to be used for 5G. 

The second phase of 5G roll out will use much higher frequencies, 20 000 – 30 000 GHz, and this is about to come sometime around 2025. Shielding fabrics are designed to withstand also these super high frequencies but are not officialy tested for them yet.

Basically, most of tests of shielding fabrics are done up to 6GHz since the highest known frequency used commercially in our daily life is WiFi 5.8 GHz. 

Our shielding silver fabric blocks frequencies from 10 MHz to 6GHz (and beyond) which includes also above mentioned 700 MHz. Therefore you’re protected against 5G with SHIELD Signalproof Apparel .

When it comes to the comparison of 5G with 4G or LTE, they use even more frequencies: 800 MHz / 900 MHz / 1800 MHz / 2100 MHz / 2600 MHz.

Can I measure the signalproof feature with a cellphone?

The answer is: Barely.

Dots or ticks on signal indicator are not accurate and each phone model reacts differently. It takes also a longer time until the phone realizes that he is losing the signal. The next problem is that you can not see the reaction of your phone inside the hat. If you put it in and then you pull it out you will not see the real status of the indicator. You would have to be inside the hat with your phone. It’s like testing the waterproof bag under the water. You simply can’t open the bag under the water to check if it is dry. And also the signal strength varies and depends on where you are. If you are very close to the emitter or antenna, then your signal indicator will maybe not drop. The thing is that the hat can’t reduce signals completely, but it reduces them to minimum and they have almost no effect on you. The only reliable way how to test the hat is with certified measuring instruments. We did it as you can see in the video above or you can do it by yourself in these places. Signal strength in the hat is hundreds of times lower than outside.

Is there some evidence the signals are harmful?

We are not saying that it’s proved or we should be scared. And the truth is that there is no official evidence that signals cause something. But there are many studies and plenty of documentaries which are dealing with this topic. And without the wind, the grass does not move. If you want to know more about this issue, here is the list of studies.

Does It really work?

Yes it works thanks to the special silver shielding fabric inside. It has a premium shielding effectiveness 35dB-80dB from 10 MHz to 6 GHz and beyond. This means that only 0.1% of high frequency radiation can penetrate the shielding silver fabric. The shielding silver fabric is certified and tested.

Silver is also antibacterial, antimicrobial, antiodor and antistatic. Generally, our apparel can’t completely protect your body against signals because it should be covered from the top to the bottom. But you can at least shield important parts.

It increases the chances of lightning strikes?

No, it definitely doesn`t.

Does it need to be grounded?

No. Faraday cage works also without ground connection regarding the hat. And signals are not amplified without earth bond.

Will signals come through other parts of skull?

If you are thinking about signals that come through other parts of head and hit the inside of the reflective cap, then pass back through the brain a second time or stay inside and multiply their power, then you have to know that it is ridiculous. The signal is not a bullet and the hat is not an amplifier. It`s like giving a question, “why do i feel cold in my winter jacket, it was supposed to protect me against cold and it comes through my sleeves, top and bottom parts.” Nothing is one hundred percent and everything depends on other factors. But in any case, you are not going to freeze in that winter jacket. The frequency of signals inside the hat is very very low and is also decreased by your skin, bones and water in the tissue.

Is this just the tin foil hat?

Our hat is not the improved version of “tin foil hat”. It`s inspired by actual situation and studies. Until now, we`ve known the waterproof, windproof or dustproof feature. Now it`s time to introduce the signaproof feature into fashion. Shield is more beautiful, comfortable and sophisticated hat than tin foil hat.

Why is the signalproof hat more expensive than ordinary hat?

The answer is: because of special shielding fabric inside the hat. Every signalproof hat is made out from the outer layer and inner layer. Inner layer is always the special shielding fabric which consists of the pure silver that assures the highest performance and has other advantages like antibacterial, antimicrobial, antiodor and antistatic feature. There are also cheaper materials for this purpose, for instance copper or steel but they don`t last long time, don`t have additional features or inhibit alergy. And silver is silver.

Why is my cell phone ringing inside the hat?

The answer is: the signal around must be stronger than the hat is able to completely attenuate. Signal-blocking hat is not a magic. It’s the pure physics. Special shielding fabric can shield only the particular amount of electromagnetic radiation. Generally, the shielding effect is up to ≈80db. If the signal around is more than this value, what is the very normal and common situation, your cell phone covered by hat will be ringing. But the received signal is reduced almost to the null. It’s the same with waterproof, windproof, bulletproof or other proof materials. If you start shooting from the machine gun to the bulletproof vest, it will fail. If you expose the waterproof jacket to the storm, it will fail. If you expose the windproof pants to the hurricane, it will fail. But you will still stay somehow more protected and comfortable than you would be without it. Signalproof feature is not 100% protection, but it’s worth having it.
