I am building an antenna with aluminum elements.
Is there any easy way to solder copper wire to the aluminum? I do not need a very strong connection, just a good electrical connection so I can then apply glue etc.
I tried sanding the aluminum and applying cooking oil, but that didn't seem to work. I will try motor oil later, but I don't think that will be any different.
The aluminum is a 1/4 inch rod.
I got it to work on aluminum foil, but it won't work on the rod for some reason?
