If you’re the kind of who worries that that the government are watching you all the time – and I mean all the time – and tend to favour aluminium headgear then you may not want to read this particular piece of research…
… especially these conclusions:
The [aluminium] helmets amplify frequency bands that coincide with those allocated to the US government between 1.2 Ghz and 1.4 Ghz. According to the FCC, These bands are supposedly reserved for “radio location” (ie, GPS), and other communications with satellites. The 2.6 Ghz band coincides with mobile phone technology. Though not affiliated by government, these bands are at the hands of multinational corporations.
Remember, just because you’re paranoid, it doesn’t mean they’re not out to get you – just ask this traitor.
