I would like to ask the correct method of making lightning rod, the best drawings
This is what I actually did at the site, and then measure the resistance, less than 4
To the ground underground, the ground dug one meter deep trench in the ground, 3 meters long, with a 50mm 2.5m 4 angle long head, sharpened into the ground, hit one meter deep groove bottom, exposing the 20cm to welding is good, then the 4 parallel with the flat steel welded together, then connect the the lightning rod leads to a strong connection, and then buried in the soil is good.
Lightning practice simple: you can use galvanized pipe set is small, each 80cm, 4 segment welding, on top of the smallest with 16mm, and the head seal made pointed, and then fixed on the house top, then the best with the lightning rod for wire
