Cellphone firm Orange says that some people don’t find base station antennas
“aesthetically pleasing”. One solution it’s patenting is to hide them inside
houses in a fibreglass box fitted to a window or air vent (GB 2359195). The box
is impregnated with graphite particles and lined with aluminium foil to stop
signals leaking out—except through a port directed outwards out into the
neighbourhood. This keeps the radiation emitted inside the house down, Orange
says.
