A friend suffers from the radiation from mobile tower. The tower appears to have a multiple frequencies, but the 2.4Ghz is the main one. I believed I calculated right, and picked up some chickenwire, with 1.5cm holes. I believe 1.5cm is too large. Can someone help me with my calculations. At the same time I am now wondering if chickenwire would be suitable and I should use a better quality wire. Any suggestions of the actual size and if chickenwire is suitable. i want to place on his area of concern on the outside of the room?
