Indeed.. if the goal is to protect the coax, you're right. If the goal is to protect the equipment inside the shack, and you're willing to sacrifice the coax, then... But an interesting question aris

Well you are thinking like a Californian. Direct strikes maybe rare in California, but in other places they are very common. I now live in a much lower lightning probability area than my Florida loca

My tower is only 55 feet, and 71 feet to the top of the mast, but it is also located on a hill and is the highest thing around for a long distance except for a very few trees about 700 feet away. NE

I am wondering - do you mean that you would bring the coax all the way down to the base, ground it there as usual, THEN back up again to the take-off point? That seems like a pretty good idea, I can'

I think that you'd need another shield ground at the point where you get close to the equipment. That way, any induced currents are on the "outside of the coax" and can flow "outside the shack" to gr
