[QUOTE="Ampdog, post: 83444, member: 144"] In my experience damage occurs more often from line surges, as would have been the case with Placebo then. If Jaco could remember whether there was a direct strike at the time (and believe me, he would remember; wonder how many people had experience of a direct strike ...) Surges occur orders more than direct strikes om homes. From the past: At the CSIR in Pretoria folks might recall a typical MW broadcast mast erected on the hill there some 15+ years ago. That was a lightning strike collector, with necessary recording equipment at its base. Would one believe that 'in season' it sometimes collected <10% of the down-strikes in the area.... Certainly not saying that home antennae should not be earthed, but because of the height above ground, such 'earths' could have enough impedance to ground to still have damage occur when direct hits happen. (One must remember that a lightning strike is a complex phenomenon mostly of many discharges, having quite a formidable h.f. content.) [/QUOTE]
