Why do you want to go 65 feet out? Seems to me the minimum distance from the tower to keep the ground rods 16 feet apart would be better. For 4 rods 90 degrees apart, that's just over 11 feet. If you

I have on hand about 275 feet of #2 bare solid copper. I also have 17 8-foot ground rods. A widely accepted rule of thumb is that rods should be physically separated by 1X-2X their length. That's bec

My 89' UST with a tall mast and lots of antennas was professionally installed and had 4 #2 solid copper "radials" about 25 feet each. First, antennas on this tower worked really well and second, I am

I would run 10 or 12 radial wires out 15'-20' to your ground rods. I would make one longer run from tower ground over to you main entrance point. I would adjust the number and lengths of radial wire

I followed the guidance and have 4 spokes of 40 feet with two rods each plus a couple next to the tower. Plus a bare buried run of 110 feet to the shack/shop Ufer foundation 250ft perimeter footing g

Art, My tower had a direct lightning hit the evening of May 9, 2019. This was observed visually by my daughter who lives on my place of 16 acres. She sent me a text asking if I knew lightning had str

This is exactly the scenario I've imagined. Thankfully, it hasn't happened here yet. I think it's virtually impossible to completely protect the equipment, at least without building a new house, but

I had a similar experience. A stack match was the only item on the tower that was damaged -- relays fused, PCB trace vaporized. But everything connected to my shack computer was damaged or destroyed.
