Figure 1. Loop Electrode in Shallow Topsoil

Use a horizontal ground electrode as a loop when the soil is shallow or rocky.

  • Route the grounding cable from the grounding connector at the mast base to around the mast.
  • Bury the ground electrode to a minimum of 60 cm (2 ft) deep or to moist soil, making a 5…6 m (16 … 20 ft) diameter loop with the electrode. Guy wires are not needed.
  • Connect the loop to the mast with two or more ground electrodes.
  • To increase the current dissipation area and minimize ground impedance, enhance the loop with horizontal radials.
Do not make the wires run parallel any longer than absolutely necessary.
