The earth connection must be implemented according to current standards. Particular
attention must be used to grounding of the antenna system, because it is exposed to
atmospheric electrical phenomena.
Remember that despite the ground link it is always dangerous to operate on the
apparatus in case of bad weather, with the presence of lightning; in fact, because of
inductance ground connections it is possible, in case of high energy discharge, that the
apparatus reaches dangerous instantaneous levels of voltage.
It is, therefore, appropriate that the equipment is installed in accessible area only to
maintenance people and only for the time necessary to repairs and inspections.
