Aluminium worked to block German Radar in WW2. Look up 'Window'. Could work if the size of the strips were adjusted to match the wavelength and laminated in layers. In a composite helmet it could work.
'Covering your Six' is a military term and would work. Army and Air Force term, they've used clock codes for directions for many years.
To the Anon that was asking about screening out signals. I took the mobile phone and Bluetooth frequencies and calculated the full wavelengths as below.
850MHz - 352mm (millimetres)
900MHz - 333.33mm
1800MHz - 166.66mm
1900MHz - 157.89mm
2402MHz - 124.89mm
2480MHz - 120.96mm
So, the wavelengths are somewhere between 35 and 12 centimetres. If you were to work at 1/4 wave lengths these would be 8.6 and 3 centimetres long, this would make it workable to put chopped strand in lengths between 8.6 and 3cm within a laminate structure with changing laminate diirections. Carbon fibre or GRP would work.
Radiofags, any comments? Have I just invented a tinfoil hat that might actually work?
Tavistock. You just had to ask, didn't you?
Watch the shills rain in here now like flies on shit.
The Brits called it 'Window' in WW2 and I explained it earlier. Same thing, confuse the radar.
5000MHz - 6cm (2cm for 1/4 wave)
Bluetooth is there (2402 to 2840 MHz)
That was the idea that came into my head, I didn't take into account the resonant frequencies that affect humans. Maybe some of the White Papers out there in Medical Land have covered this and the concerns to human health?
Humans are 95% water, so the answer may lie in the humble microwave oven.

Sorry Anons, it appears that In threw a grenade over the wall when I mentioned a 'T' word that particularly triggers them.
I need to 'Take Stock' of what I said.
