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.
