I was standing under the front porch watching when a lightning bolt struck the cell tower 150 feet away in front of me! Tower survived but it never had its red light on at night anymore since then. When I walked into the house after the lightning strike, the 2 tv's didn't work anymore! The cable was connected to which came from the cell tower! So as long as there are any structures or tree's taller than your house, I don't think you need a lightning rod! I feel your pain. 6 or 8 years ago a lightning strike blew out both of my tv's. We had satellite tv so it had to come through the electric wall socket (I think) Should have listened to my gf when she said to unplug during electrical storm. Now I do even though I have circuit breakers installed. The LED tv was fixable but the old analog was beyond repair. Link to comment Share on other sites More sharing options...
bastonjock Posted December 11, 2018 Posted December 11, 2018 It's best practice to unplug everything in an electrical storm, I would even disconnect an earthling system ,the power from the lightning strike can run under ground and pick up cabling into the building , all so referred to as an earth spike There is no guaranteed method of 100 percent defence against lightning ,its risk management ,you can reduce the risk by running a conductor on the out side of your house ,the idea is to stop the lightning going through your house All metal can melt ,the two most popular metals for conductor are copper and aluminum,copper has a much lower resistance than aluminium and is not so prone to other problems that you get with aluminum 1 Link to comment Share on other sites More sharing options...

Forum Support Old55 Posted December 11, 2018 Author Forum Support Posted December 11, 2018 Tom asked why attract a strike. My understanding it’s in order to provide a safe direct path to earth ground. And my question is how is that done? We know its as simple as an iron rod attached above a structure well insulated from the structure with a large gage conductor connecting the rod to ground. Simple but what exactly are the guidelines for this? My folks live atop a tall hill now and we were thinking a lightning rod would be a great preventative tool. 1 Link to comment Share on other sites More sharing options...

And I found out they still use lightning rods but they are called "lightning protection systems" now. This may be necessary because global warming is now "global climate change". But here is what I got from it: Quote Lightning protection systems are the modern development of the innovation pioneered by Benjamin Franklin: the lightning rod. Today, lightning protection systems are in use on thousands of buildings, homes, factories, towers, and even the Space Shuttle's launch pad. This article will examine why lightning protection is necessary and what the systems can and cannot do. Link to comment Share on other sites More sharing options...
