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.
