Ans : Earthing or Grounding an object/tower means providing an electrical connection between that object/tower and mother earth. This electric connection is achieved by running an electrical wire/strip between the tower and an earth electrode. Earth electrode is a metal plate/pipe/sphere properly embedded at a depth in the earth. This Earthing/Grounding of tower is necessary to :a) Prevent damages to delicate instruments or humans due to stray voltages/currentsb) For optimum performance of the communication system.
