Questions - perhaps stupid ones - regarding Polyphaser Protectors

Sorry if this is a stupid question; would just like to confirm whether I've got this right or not, since I'd rather not purchase something that my present listening location would prevent me from being able to appropriately install. Either the Polyphaser or the I.C.E. can be connected to a ground line. It's just that the quality of the ground line is a huge factor in the safety of the system. A bulkhead point ground -- called a ground window -- is the best. Next best is a ground strap. Why? Because lightning is mostly RF and is subject to "skin effect" -- that is, it travels mostly on the surface molecules of a conductor. Strap has the most surface of any kind of wire. One detail I've never seen described is the attachment of the copper (flashing) strap to a ground rod. Is it adequate to simply tie it in place with wire or perhaps wrap it around about 270 degrees and clinch it with a couple of bars and some sort of anti-oxident? A controversial choice is braid, but I won't go into why here because it's a long diversion. Last is a simple copper wire to your ground -- in your case, the cold water pipe. Bottom line: Given the same type of ground (in your case, a wire), the Polyphasers and the I.C.E. will outperform the others. Go ahead and use an I.C.E. or Polyphaser with a ground wire. Eric Thanks again, Junius |
