Far as I'm concerned, when it comes to Mother Nature, all bets are off. We had
a nearby strike a few years back. Lost most appliances (was before I was a
Ham). , and power company had to come out and get things settled again. When
the lineman was done, he brought half of the Ceramic Insulator that was left on
the pole. The ceramic was MELTED, and I found the balance of the melted ceramic
chunks lying on the ground in a 40 foot radius from the pole. If it hits, It's
gonna hurt something if it has a mind to, no matter what YOUR plan is for it.
Now, I have none of my radio equipment grounded, cuz lightni is TRYING to get
to ground, right? It's worked so far, so it must be right. (Toungue in
cheek.... kinda).

The put your coax connector in a glass jar is an old ham's tale. NOT
EFFECTIVE!
Glass canning jars are good for maybe 500 volts tops. You may find
lightning at 100 times that.
Also, the energy in a surge heats up the air inside the jar, increasing
the pressure, which can splinter the jar.
And, if the jar has any remnants of metallic seals or labels, or a wire
lid hold down, it will charge those spontaneous electrodes to harmful
voltages.
You need a smooth path to earth, no sharp bends in your earthing
conductor. A minimum of no. 8 gauge wire, and preferably no. 6 gauge.
Earth leads need to be clamped or welded, never soft soldered.
