Just saw this video so thought i'd share, ingenious idea as it's so simple. Would be so easy to make with F Types!
Can use a cheap actuator...

Wondering if RimaNTSS or Trust1 will build one..
 
That's a cracking idea, I remember as a kid when there was thunder and lightning my mum & dad would switch off the TV, pull the plug out from the wall & pull the coaxial cable from the TV as well. I have got to admit both my dishes are wall mounted and not even as high as the guttering and I have no aerial feed so I have been taking the risk even when at home.
 
Most lightning could jump that gap (in a flash).
 
Lightning goes where it wants to, I remember taking apart a computer at the shop where a lightning bolt had hit the customer's phoneline, travelled through the dial up modem, and the bolt went through a PCI sound card to the bottom of the case like it wasn't there, scary stuff...

Might not do that if you bolt a hefty cable from the fixed bracket to a proper grounding rod just outside the building - lightning current will follow the path of least resistance. Even better, run the cables through a similar bracket OUTSIDE the house before they come inside and connect the grounding lead to that - combined with the "quick disconnect" rig, that should mean that the lightning currents should not cause much (any?) damage inside the building.

My Mum would open a window too....'to let the lightning out'.....
 
I would comment but :-rofl2
 
My grandma would never touch any cutlery in the house during an electrical storm. Not sure where that superstition came from.
 
Summat to do with Forked Lightning ? :ph34r:

Probably would not (or at least "should not") have touched metal door handles, kitchen pots & pans, etc., (etc., etc.,....) either :-lmao

Sounds feasible. These ideas do pass down the generations, this one probably starting with Benjamin Franklin and his key on a kite...
 
My dad was a fireman and they had a few shouts to the aftermath of lightning strikes, the strangest one was a direct strike to a TV aerial, it jumped the gap from the coax behind the tv to a radiator and blew it off the wall. The TV was still working when they arrived.

That's a really novel idea and while it may not protect everything from a direct hit it will reduce the possibility of front end damage from nearby strikes. Some years ago with a storm a few miles away I started hearing a clicking noise from my radio room. Went in to find it was being produced by sparks jumping the gap across a PL259 that I'd unplugged from a radio, it wasn't even a large antenna, just a vertical dipole for 6m.
 
@aceb
Seems to (if it was not "obvious") confirm that lightning energy takes the easiest/shortest route to "true" ground/earth - in other words, the "best" protection is to make sure that the energy is diverted to "ground" before it ever gets inside a building.
