Bicycle Rim Magnetic Loop Ham Radio Antenna - Homebrew de KK6FUT. Post #1210.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=e3_Iaf7dIo0. This antenna project is one of the things that makes Amateur Radio so fun and fascinating--turning junk into something useful. In this case, KK6FUT has converted an old bicycle wheel/rim into a homebrewed magnetic loop antenna for the 15 meter and 20 meter ham bands.  The loop is made from a discarded bicycle wheel/rim after the spokes have been removed. KK6FUT made slits with a hacksaw and used an old AM/FM variable capacitor for tuning. While this loop is primarily for receiving, it can be used to transmit with a 4 to 5 watt signal. SWR measurements are quite good--1.0:1 on 15 meters and 1.4:1 on 20 meters.
