The performance optimization of fixed wire-broadcasting distribution antennas in 5G communication networks

In telecommunications companies, a protective earthling device must be installed if there are no connecting lines and remote power supply circuits for equipment that uses earth as a wire. In communication companies, if the “minus” ground of the current source is the ground, it is necessary to equip a working protective grounding device (in this case, remote power circuits can be operated according to the “wire - ground” scheme) or the “plus” ground of the current source, but of the “wire - ground” scheme No penalty for remote power supply as per In this case, the connecting lines can be used as the “ground” wire of the circuit. The circuit of the work-safety grounding device must have independent inputs to the building (to the ground shield) in the presence of remote power supply circuits. Companies must equip separate working and protective grounding devices if there are remote power supply circuits according to the “wire-ground” scheme, grounded on the “plus” of the current source.
