Ham radio operators would disconnect the antenna, place the
antenna lead inside a mason jar, and still suffer damage.
Only dumbass hams, and some CBers did that stunt. About a
stupid trick...Like a little glass bottle is going to stunt a
strike that traveled a few miles in *air* to get there...
When I ground out my feedlines, it's to a good ground, and
is totally outside. When I take a strike, or even a close
non direct strike, you can hear those feed to ground
connections arc, even though they are connected by
so-239's/pl-259's. I've never had any trouble using that
method, and I've had two direct strikes to my mast in the last
4-5 years. My mast directs most of the energy to ground,
but you still have some current on the lines that needs to be
cleaned up. You sure don't want to run it into the house...

If the coax is elevated, and not snubbed to ground at any
point, the strike potential at the end of the feedline will be
*HUGE*. Disaster city... That much potential can travel halfway
across a house looking for ground. Usually will seek plumbing,
toilets, etc. I've heard of toilets being blown to bits in a case
like that.
