There are people who lost their electronic equipment in the house including radio, tv set etc. because of a little bit of lightning near their house.
Trees are not exactly lightning rods. I would strongly suggest to ground the pole using a round steel of about 1/3" (about 10mm). There should be some grounding point in your house, where you can connect that round steel to. You must not use electric wire for that. And I strongly recommend to place that outside your house at the wall. In case there is no such thing as a grounding point, you need a bar of stainless steel, again about 1/3" (about 10mm) and at least 18 feet in length. The whole thing you drive into the earth. The upper end that looks out of the earth you can connect to instrument pole. As 18 feet are very long, bars of about 3 feet are provided including a thread at the end to connect one to the other. And there are special devices to drive the bar into the earth by vibration. morr...@gmail.com schrieb am Montag, 17.
