Can a lightning rod be made of a hollow stainless steel tube? Is it better to use the wires or other lines? Do not want to use iron ah, iron rust ah!
Hollow, with a tip at the top. The bottom line shall be galvanized round steel or galvanized flat iron, and the place where welding is painted shall be painted with anticorrosive paint
A hollow stainless steel tube can be used to make the lightning rod. The ground is full of cables.
Make sure the cross section of the lead line is enough. In general, it is possible to measure the resistance by less than 10 euro with a low resistance tester. It doesn't matter if you use it at home.
