to proper grounding for the mast and supporting structure, grounding of the lead-in
wire to an antenna discharge unit, size of grounding connectors, location of antenna
discharge unit, connection to grounding electrodes and requirements for the grounding
electrode.
The cable distribution system should be grounded (earthed) in accordance with ANSI/
