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.

A different idea than lug connections, is to use load-center style ground
bars bolted to the metal plate.

I fully agree this is not up to Bellcore grounding standards. 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.
