If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=OuaTCZG2EBs. Here's another interesting magnetic loop antenna that is a bit more complicated than other magnetic loop antenna videos online.  According to Rob (dx2hunt), this dual magnetic loop antennas covers amateur radio frequencies between 80m and 17m continuously.  The 3/4-inch (19 mm) copper loops are arranged in a parallel fashion and are separated by 2.5 to 3 diameters of the copper tubes.  The most expensive part of the antenna is the vacuum variable capacitor which has a range of 25 to 1,000 pF with a 7,500 volt rating.  Rob says he has made some good contacts between Australia and New Zealand with this dual loop magnetic antenna.  If you've got the time, you may want to build one of these intriguing antennas.
