Aluminum conducts fine as long as you take care of contact oxidization. I can't see any reason why it wouldn't work. Possibly one of the "CB dudes" knows a reason not to use AL. Ron
I am fixing to install a CB in my FJ. My question, I will be making my own style mount for the Antenne, can I machine it out of a solid chunk of 7075 aluminum bar stock or does it need to be steel for grounding purposes ???
