Thank you for your response.
I'll be using a steel ham tower that I picked up on auction. Total length / height is 12 mt, it's triangular in cross-section.
The bracing on the tower will be steel cables that have been recovered out of a 50pair telecoms cable. I've not quite decided on the number of brace points yet, but either 6 or 9 makes sense. ( I'll have to take into account the weight of the finished turbine)
As for hitting the water table, it's 25 mts down at my borehole and the house is about 3-4 mts above the top of the borehole . So work on a 30 mtr drop. We are not likely to drive an earthing bar that deep. ;-)
My main concern is a direct strike on the mast, as this will light up my battery bank quite spectacularly. Not to mention anything else that is in the way. The batteries will be housed in a seperate structure that is 5mtrs from the main house with a distribution cable running from there into the house. Additional power from PV panels (future project) will also be routed to this room. All of the required equipment will be housed in this room. Inverters, Dump load / charge regulators etc.
I am planning on earthing all of the equipment that can be earthed in this room directly onto 12 mm (1/2 inch) copper earthing bars driven into the ground.

after every hit you have to inspect the whole system again
Ouch, thats what I want to avoid, the idea of getting hit once does not appeal, multiple hits is not my idea of a picnic.
Thanks
