[TowerTalk] Tower Grounding and Lightning Protection

[Jim]

BTW, a polyphaser (or any coaxial lightning prevention device) is not designed to mounted outside on one of those clamps that clamp to the top of a ground rod. They are not weatherproof.

 

In the commercial world, the polyphaser is just inside of the building.

I have one, about 3 years old, strap from the grounding system into my SPG on the entry wall. Not buried, used the Harger copper bearing grease. It's tight. But I see your point.

 

I've seen them with an X cut in the strap, pushed down over the ground rod and silver soldered. It was pretty, but I didn't want to spend the time on my knees with a torch, and there's #2 cadwelded to the top of this rod running to the service entrance bond.

 

Good luck.

Not the best way. But fine...

 

They corrode

They loosen up, I was never able to get mine to tighten up without spinning on the rod.

They are not NFPA 70 approved (National Electric Code) They are not UL approved.

 

If you have information to the contrary, please supply.

 

Thanks
