To be a Faraday shield the enclosure must have no holes larger than a
wave guide at cuttoff to the highest frequency you want protection from.
By this definition a tower is not much of a Faraday shield.
Further most lightning damage is caused by the raising of the GROUND
a few thousand volts or more. A Faraday shield is no protection when
ground is raised.
