I would be surprised if a Pringles can can do it. This stuff is symmetrical. If signal can get in and out from one end, it can also get in/out from the other, meaning MI6 would be able to listen in on their diplomatic correspondence. So there’s probably a serious Faraday cage around the place.
- dingaling 9y agoA Faraday cage at building-scale is just that, a cage to attenuate omnidirectional signals. The Pringles antenna for wifi, or a Yagi or parabolic dish, is strongly directional and can pass through the voids in a cage when aligned. It just needs 12.5cm between the cage elements, like a window.
