I decided to use PVC pipe, about 50mm dia. extending 2.5m above the roof line. Lighter to handle and not too flexible. The cable is easily run down the middle, to the wireless transmitter, which is mounted on a wooden pole.
I don't know if it would make much difference in enticing lightning to strike, but as Karen said once the ionized path is created no vapourization of the wire is going to stop it. Neighbours of my mother had a bit of electronic kit attached to their back wall with a small wire running upwards - I forget the details. The wire vapourized all right, but not without scattering bits of circuit board and components all over their yard. Luckily, no fire resulted. There are plenty of high gum trees nearby, and TV aerials with metal masts protruding from the roof.
