It's amazing what can be done with discarded materials in the realm of amateur/ham radio. In this video, Australian radio amateur Peter Parker (VK3YE) uses an old bicycle tire rim to make a workable magnetic loop antenna for listening and WSPR transmitting over 7-28 MHz. While not as efficient as a commercial magnetic loop or even a dipole antenna, it does work. You could even use an old "hula hoop" from "back in the day" to make a receiving loop. If you're careful in selecting cast off materials, you may get an antenna form absolutely free. You can't beat that deal.
