Articles 810 and 820 of the National Electrical code, ANSI/NFPA No. 70-1978, provide detailed information regarding the grounding of (a) the mast and the supporting structure, (b) the lead-in wire to

13、an antenna discharge unit, and (c) the coaxial cable system. The Code also specifies the size of the grounding conductors, the locations of the antenna discharge units, the connections to the grounding electrode, and the requirements for the grounding electrode. An example of an installation meeting

14、 these requirements is given in the attached illustration, IL0153. Audio Output Obtain a single-conductor shielded cable of suitable length to connect the Audio Output jack on the back of the chassis to the Auxiliary or Tuner input of the sound or communications system. Terminate one end of the cabl
