I use the jar because it keeps my all my exposed grounds and lead-ins not dangling loose on the floor when they are NOT connected to my gear. I also have an expansive ground system of 8, 8 foot ground rods, static discharge units, and centralized grounding bus, all located outside. Two years ago a vertical 10 meter antenna I had up took a direct hit, guess what? The jar did not explode, and none of my gear had any damage. However, I did lose a wall phone, fax machine, and wi-fi hub, the energy actually knocked the phone off the wall. A friend who now uses a jar does so because he noticed that he got little burn marks in his carpeting caused by static discharge going across his PL259's while they were laying on the ground embedded in the carpet.

Lightning looks for ground to complete the circuit, not unterminated/ungrounded feedlines, there is no reason for the bulk of the energy to dissapate to the jar, I have provided a better path for this. This is what works for me, I use it in addition to my ground system, not AS as ground system.

I always see people posting on various message boards of how they seen this or that, adverse to the original post, but rarely do you see these adverse claims actually supported. I have been doing this for well over 30 years, and never have I've seen or heard of the "exploding jar" until you posted it here, although I agree that it could be plausible if someone used the jar without any type of ground system. Nevertheless, googleing the term "exploding jar lightening" returned no results of anyone experiencing this. The only results returned seem to suggest that most use the jar to contain any possible small static discharge that may be on the feedlines. Amateur's have been using glass containers since the dawn of ham radio. It is not my suggestion that anyone do what I do, but this is what has worked for me for years.

So anybody who reads this, DO NOT DO WHAT I DO! DO NOT use a jar to rest your feedlines in during a storm it MAY EXPLODE!!!!

Edit: I stand corrected, I was able to find one other claim of this. However, there was no mention that a ground system was in use.

[QUOTE="295, post: 147018, member: 9162"] I use the jar because it keeps my all my exposed grounds and lead-ins not dangling loose on the floor when they are NOT connected to my gear. I also have an expansive ground system of 8, 8 foot ground rods, static discharge units, and centralized grounding bus, all located outside. Two years ago a vertical 10 meter antenna I had up took a direct hit, guess what? The jar did not explode, and none of my gear had any damage. However, I did lose a wall phone, fax machine, and wi-fi hub, the energy actually knocked the phone off the wall. A friend who now uses a jar does so because he noticed that he got little burn marks in his carpeting caused by static discharge going across his PL259's while they were laying on the ground embedded in the carpet. Lightning looks for ground to complete the circuit, not unterminated/ungrounded feedlines, there is no reason for the bulk of the energy to dissapate to the jar, I have provided a better path for this.
