Hi, David and all;|
3-5 parallel copper wires spaced 2" or more is as good as copper strap. Compare the cost to decide. Greater separation and more wires will further reduce the inductance, which is what you are accomplishing with a wide strap instead of a cylindrical wire. I see no problem running under the roof as long as you maintain ample distance from wiring, plumbing, or any other conductor.

Copper strap will be used in two places, each side of the garage, to run between the tower base and the grounding system, about 50' each run. We live in a low lightning strike region.
