Hi Bob.
As a matter of fact, if you have a substantial amount of copper, it might
work. I have heard of people using the chain link fences around their
yards as a ground plane for a vertical, and very successfully. And, if you
are lucky enough enough to have a steel building on your property such as a
garage or barn, you've just hit the jackpot! As a minimum, you need
radials of at least 1/4 wave in length for the lowest frequency you will
operate on, but if you want to look at it another way, that is a
minimum. In actual practice, the more metal the better. That is the
principle behind a mobile antenna installation on a car.
So, let your imagination go to work and see what you can dream up.
