Well now after more than a few days looking, I find myself back to where I started.

The best signal attenuation rated garment for body protection I can find is this:

The only other material that equals the above shielding effectiveness I can find is this:

Suggestion;

1. Buy the protective vest or;
2. Buy the fabric above and create your own clothing (note nickel is / can be skin reactive and is difficult to wash so if you do that means you likely need to sandwich the nickel layer above between an outer and inner layer.

Alternative fabric supplier (none certified, unlike the above);

Significantly either the garment above or the recommended material should shield against the new 26/27 GHz 5G frequency (unlike most materials).

With a lot of head-scratching and a little innovation you could likely make an effective though very, very small faraday tent to sleep in using these;

In the .pdf I costed for min 6 sheets; I think I could likely build an emergency shelter with just two (?).

Why a negative ion generator might help per Dr Duncan?

"A cyclotron accelerates charged particles "

https://en.wikipedia.org/wiki/Cyclotron

The negative charge must cancel out the positive charge on the cyclotron charged particle stream?

Extremely High Threat Frequency Bands

50 - 750 kHz - Carrier Current Bugs (power, phone, HVAC lines)

25 - 80 MHz Ultra low power devices (micro watt devices)

65 - 130 MHz Micro power Part 15 devices (FM broadcast band)

130 - 150 MHz Body Wires and Wireless Microphones - Band I

150 - 174 MHz Body Wires and Wireless Microphones - Band II

174 - 225 MHz Body Wires and Wireless Microphones - Band III

295 - 310 MHz Spread Spectrum and Micro powered Bugs (micro watt devices)

330 - 440 MHz Audio/Video Bugs (398.605, 300.455, and 399.030 MHz are popular)

430 - 550 MHz Audio/Video Bugs (433.920 and 418 MHz is popular)

800 - 990 MHz Audio/Video Bugs (902-985 MHz ISM band is popular

1.10 - 1.95 GHz Video and Audio (980 MHz to 1.45 GHz is very popular)

2.00 - 2.75 GHz Video and Audio (2.4 to 2.45 GHz is extremely popular)

5.60 - 7.50 GHz Video and Audio (5.8 to 6.2 GHz is becoming very popular)

8.10 - 13.00 GHz Video and Audio (Popular)

850 - 950 nm Infrared Transmitters


Don't forget about the specific propagation and absorption bands. Bugging devices operating below 22 GHz are very inexpensive, and easy to buy. Devices operating between 22-60 GHz are more expensive, but just as easy to secure. Devices operating on frequencies above 60 GHz tend to be expensive, and can be very difficult to obtain.


DC - 3 kHz Typical Audio Band

3 kHz - 500 kHz Skin Effect (Non Radiating)

500 kHz - 3 MHz Non Radiating, Conducted RF

3 MHz - 300 MHz Conducted RF, Free Space Radiating

300 MHz - 3 GHz Free Space Radiating RF, Slightly Directional

3 GHz - 22 GHz Free Space, Low Attenuation., Highly Directional

22 GHz - 60 GHz Water Vapor Absorption Band

60 GHz - 3 Thz Limited Usage For Covert Surveillance
