Hi all,
I believe most of us have encounter lightning strike problem. So let us share our experience for the best practice to avoid lightning problems.
Best regards,

No luck. Strictly science. If you are in your car, and a power line falls across it in a storm, what is the recommended course of action? DO NOT GET OUT! Do not complete any circuit to ground with your foot. The tires will insulate you. Rubber and air. Great insulators.I call that lucky Tim,
There are ground paths through your ethernet and power supply.
Or are you running fiber on the ethernet and an isolation transformer for the power?

so no grounding whatsoever? do you insulate your antennas using rubber or something? Last year I had a lot of issues with surge's via lightning, went right through the ethernet cable to the RB and wireless card all went dead. But considering your using solar and air, No surges Nice -Jordan BNo luck. Strictly science.

I use solar power/batteries for these applications, and all radio for internet connection. No connection to any ground at all. Good thing! One of those boxes I bought from you!
In a car there the insulation isn't made by the tires, but with "Faraday Cage" rules.No luck. Strictly science.

http://www.youtube.com/watch?v=RvG3ieOh8cIJust a question...how many people have been driving in a car and the car was hit by lightning? Or the car in front of you? Or next to you? Or going the other way? I guess it is because nobody has the nerve to drive in a storm!
The first video: The damage was "Oh my God!", and replaced the antenna. The car stopped because of the flat tire. My question is; Did the lighning blow out the tire? Or did they have a flat, lowering the resistance to ground, and then get hit?http://www.youtube.com/watch?v=RvG3ieOh8cIJust a question...how many people have been driving in a car and the car was hit by lightning?

Good theory! So, how many cars have you seen hit by lightning? 10? 20? 100? Gotta be a lot if that is true. I have yet to see even one in my 40+ years of driving. The Faraday cage effect will NOT prevent a lightning strike! Only protects the internals from damage. The electricity would still be conducted to ground around the cage.I call that lucky Tim,

I don't think tires will insulate you at all... first, tires and road and car metal parts are all soak wet so there practically is no insulation, also the lightning electricity has already travel thousands of meters, how in the world will 7 - 20 cm. of wet rubber act as an insulator... that's a non-sense ... is the faraday cage effect what's rule there...
If the equipment is connected via RF and batteries and solar power, and floating ground and whatever you may suggest... once in a lightning strike path it will kiss moma good bye anyway no matter what...
If you are interested in this topic, you need to see this video!! In theory, this is what I am using. I mentioned this video in an earlier post, but now feel it is so relevant, I want to draw special attention to it. Like I said before, the Faraday cage effect does not prevent a lightning strike, but it does protect the internals. Even the FM stereo was undamaged. The results would be drastically different if he had a ground wire between his teeth.http://www.youtube.com/watch?v=ve6XGKZxYxA -- another good one from our friends at top gear
During a lightning strike, there is very little air in the electron stream. It has been superheated and expanded to the point that the electron stream creates its own "vacuum tube" with the walls held out by the air against the outer boundary of the stream. The thunder you hear is the electron stream ejecting the air.resistance of a tire, ok... where's resistance of an air? or an air is pure conductor for now?
