Lightning rod for a yurt in an open field?

[UKadventurer]

This is an old thread but I thought I'd add my tuppence worth.

We live in a high valley in the Mongolian mountains about 1700m (5500'). It's grassy and there are few sparse trees then 100m to a forest. My 2 gers were pretty expensive and there are lightning storms frequently in the summer. We have a compound with 2 shipping containers and 2 gers with a gap of about 3m between each ger. We've also got an older traditional ger but I'm not bothered about that. We use it infrequently mainly for cooking when guests come.

The science, as I've read it, says that lightning can strike anywhere. Although the risk is low. Just because there's a few trees nearby doesn't help much. They recommend having a lightning rod no more than every 6m (20'). I'm going to put a lightning rod on the crown of each ger, string copper braided wire between them, then over to my 2 x 20 tonne, back to back, shipping containers. Each rod will be at 4m height which gives a cone of protection 4m in diameter. That's sufficient for each ger. I bought 3 grounding rods. Which I can arrange as appropriate. Probably in some sort of triangle arrangement.

I think it's cheap protection for a low-risk but potentially disastrous scenario. However, we are in a high risk area. We've had lightning all around us several times already. Just the fear factor alone is worth mitigating.
