Thanks for the info. It makes sense. Im a Amatuer radio operator and was also wondering how much rf would be generated. I dont want to destroy my equiptment thats in a room about 20' from the garage. The worse thing is that i have antennas fairly close to the house. The chicken wired sounds pretty sweet and will probably reduce the rf radiation by directing of it of it to earth ground and also result in a safe operation environment for inviting friends over to view the lightning show.
Thanks for the feedback.
High voltage isnt for every one.
Be careful
