Aluminum for grounding and bonding?
Copper prices are out of sight! Can aluminum be used instead? Would larger gauge be required?
Thanks and 73 de N0RDE Jon
I use a large aluminum sheet for my station ground plane and an attached aluminum buss bar. So yes, aluminum can be used for your grounding needs. I still have copper strap out to my copper grounding rods however. The big drawback of aluminum wire is its tensile strength is about 40% less than copper wire, so it is more likely to break. But with limited runs and the ability to visually inspect your connections, aluminum wire should be fine. I don't think a larger guage would be necessary.
