Well apart from using the lightning tracker on BOM , and disconnecting the tower and all your modems etc when lightning is about, can some type of specialised fuse be added into the system?
I should ask my solar installer as I suppose this is a similar problem with a Solar panel where the frame is required to be fully isolated from the structure.
What stops the inverter electronics getting fried?
