Which spectrum do you wish to block?
700 MHz? Faraday cage. It’ll penetrate a concrete floor or two.
Millimeter wave? Double pane windows and the logs will stop any cellular millimeter waves from getting into your house- especially at the distance you are from that tower.
Please understand that 5G uses a range of spectrum.
Totally get that. Was trained to provide total EFI screening for MRI facilities....
So, is a Farraday cage to cover 15 acres of land up to a height of 100’s feasible? Absurd........problem isn’t a technical one, but a practical one......
