Radio amateurs have used almost anything made of metal for antennas. How about using common aluminum foil as an impromptu or emergency antenna?
In this fascinating video, David (DL1DN) experiments with a rolled-up piece of aluminum foil as an antenna for the 10 meter Amateur Radio Band. Believe it not, the antenna works. You have to see to believe this.

Here are some comments from David (DL1DN):
Awesome 20cm antenna made of aluminum foil. I just test this stupid antenna and it works 😉 Check what is possible with QRP and 20cm antenna. 73 David DL1DN
