Inadequate earthing is the most common cause of poor fence efficiency and interference with radio equipment. Common causes of inadequate earthing include dry soil, insufficient burying depth of earthing rods, insufficient number of earthing rods, or wrong earthing rod material (e.g., rebars that lose conductivity when rusted).
