    Please note that beer cans in the 50s were made of steel, which could be soldered together. Don’t bother trying to use aluminum cans! Some veggie cans are still made of steel, and you can use those.

    This predates the `50s, according to my ham-radio-aficianado uncle — these were put together out of any large series of cans and a lot of solder. The wide availability of beer cans during and after WWII made it popular.

    Uh, this is not based on the same principle as the recently popular can-tennas. This one is using the cans as the active element. The can-tennas use a wire as the active element and the can as a wave guide.
