Ive seen what it can do to a amp and a cb. Pretty my melted them together and blow the batteries. Wasn't a pretty site to see 2000 bucks down the drain.
I don't think a glass jar will contain the 1.21 giggawatts potential of lightning.

Did you all take notice THERE IS AN AWEFUL LOT OF ANTRON 99s getting hit by Lightning

Absolutly the truth. My body was charged. Ask a doctor. I lost a computer and scanner. My cb base was unharmed, figure that outlinx wrote:Wait a sec.

The human body can act like a capacitor. For instance when you drag your shoes across a rug in the winter. The static charge is quite substantial but builds on the surface of the body rather than inside. Faraday put it this way:
"Faraday established that static charge resides on the outside surface of a conductor. This also applies to partial conductors like the human body and because of mutual repulsion and mobility the charge will be distributed on the body so that its density is proportional to the body curvature. In searching for a basis on which to calculate capacitance we note that a sphere of radius about 0.8 m is a reasonable first approximation to describe the location of charge. If we use this sphere as a model then electric fields a few metres from the body will be accurately described. Close to the body the charge clusters at extremities of the body and the totalcapacitance will tend to be less than that of the proposed spherical model."
The resulting static charge will be completely discharged with the first proximity opportunity to ground (including another person). The probability of carrying a charge all the way to a hospital is minute.

Re: lighting and antennas
There is a much greater chance during a storm for static buildup in your antenna to cause damage than for a direct hit to occur at all.

I heard rumors about the glass jar. you know I think I would rather be struck by lightning itself than to be struck by lighning and glass!

420Snowman wrote:Well, what happens if your antenna is NOT grounded, does the charge run straight back through the coax and burn the roof, siding, drywall, and whatever is in its path??? And if the antenna IS grounded, does the charge choose to go down the copper wire to the ground rod RATHER than going down the coax?? Electricity takes the path of least resistance, correct??

YES and yes to all. I live it south Idaho with many t storms here it the valley. I ground everything!

JSM201 was right on the money in his post, the electrical charge in the air doesn't have to be at lightning strength to cause damage in electrical components, ground your equipment properly. If possible unplug your coax and your incoming power before a storm. Update your insurance policy, they need to know you have the equipment before you try to make a claim.
Good feedback! Just make every precaution. Then pray!

Re: lighting and antennas
Then I heard a hell of a storm outside. Got up and went to turn on the lights and had no power. Lightning hit the power line coming in the house, not a 40 foot tower in the yard , and smoked everything plugged in the outlets, ( tv, computers, amp, stereo, and worst of all, my coffee pot).
Luckily my homeowners insurance paid for most of my junk.
