I use these ground bars. I don't like soldered connections outdoors. I picked up my ground bars at a hamfest. They are made out of copper, not aluminum. Does anyone know where I can purchase the copper ground bars today?
If you use the aluminum ground bars with copper wire I'd use an al-cu anti oxidant compound like Penetrox.

But seems much more ham-amenable, especially for those of us who unroll many of our random-gauge radial wires across driveways and lawns on contest weekends and hook up in cold weather - the clamp screws in the ground bars are easily worked with a screwdriver in a gloved hand and accomodate any random-sized-style conductor.
