Non-standard foundation for fixed installations of broadcasting nodes and collective television reception systems in Wireless communication

The resistance of protective grounding devices of intermediate points without power supply installations should not be more than 10 ohms for soils with resistivity up to 100 ohm-m and not more than 30 ohms for soils with resistivity more than 100. Resistance, strong points of work or work-protection foundation devices of linear hardware outlets; According to the “wire-to-ground” scheme, serviced amplifier points or regeneration points that are not remotely serviced must be determined based on the voltage drop across the grounding device from the remote supply current not exceeding 12 V. However, the work resistance or work-protection basic devices should not exceed the values. Resistance standards of grounding devices for unattended amplification points Long distance communication and selected communication intermediate points may change its values. Remotely operated unattended amplifier points (PUP) must have three separate grounding devices, working, protective and linear-protective, according to the “wire-ground” scheme where the remote power circuit is terminated. In cases where metal tanks do not need to protect NUP or RP from corrosion, as well as when non-metallic bodies use NUP or RP, an integrated protective grounding device must be installed.
