I am installing ground straps between a garage roof mounted tower (at h=30' above ground), and a grounding system consisting of a perimeter loop of #2 ground wire, multiple ground rods, and several U
Is this strap or copper flashing? If it is strap, I'd never use it for anything in a lightning ground unless the lead needed to be flexed. 73 Tom _______________________________________________ See:
Go to your local scrap metals dealer for copper flashing. I picked up about 15 feet of 6 inch wide flashing, the kind they used for roofing, for around $12. It is around 6 inches wide but can be cut
Hi, David and all; 3-5 parallel copper wires spaced 2" or more is as good as copper strap. Compare the cost to decide. Greater separation and more wires will further reduce the inductance, which is w
What importance does inductance have in grounding a roof mounted antenna? I would think impedance is the prime concern. Keith NM5G Hi, David and all; 3-5 parallel copper wires spaced 2" or more is as
At the frequencies involved in lightning (IEEE says the energy in lightning is broadly centered around 1 MHz), the impedance of the earth connection is, for all practical purposes, entirely dominated
