Common use of Faraday Cage Clause in Contracts

Faraday Cage. A Faraday cage provides an EMI shield to further reduce noise. The cage usually consists of multiple conductors in a box like configuration. A halo ground system with multiple down conductors can act as a quasi Faraday cage, and give some low frequency shielding. When lightning hits the tower, the tower will pass the current to ground and radiate RF energy. A Faraday cage can reduce this energy by adding distance (as seen by the magnetic field) between the tower and the equipment shelter. The steel reinforcing in the concrete shelter walls can form a highly effective Faraday cage if bonded to the grounding system. The amount of shielding depends on the size and spacing of the welded wire fabric. Additionally, all rebar must be bonded together.
