the conductivity means nothing in the end....
I should qualify that . Because the lightning has just traveled several miles through a virtual insulator (Air) the last few meters via the mast means nothing to the strike. Conductors of varying resistance will still take all current to ground but the ability to conduct or more importantly not conduct, is seen as heat. So a poor conductor has a greater chance of being destroyed.

Probably won't be safe even then. The safest measure is to place it inside say the oven. Metal casing all around (faraday case) stops the magnetic field from destroying the electronics. I can just see you now trying to stuff a radome in the oven ;-)
