Simple Ham Radio Antennas--100 watt 7 MHz magnetic loop for units and apartments

If you're having trouble viewing this video, please enter this title link into your browser search box:  In this well-produced video, Peter Parker (VK3YE) shows us how to design, build, and use a 100 watt 7 MHz magnetic loop antenna for restricted places such as apartments or in areas where HOAs and CC&Rs are present.  Peter says there are no hard to get parts or complex workshop skills needed to build this portable antenna.  Instead of an expensive vacuum variable capacitor, Peter uses a length of RG-213 coaxial cable (approximately 1.85 meters long and 3mm circumference loop for 7 MHz). The sliding capacitor dimensions are approximately 6 cm x 8 cm.  Since this loop carries a lot of potentially dangerous voltage, please use this antenna away from your shack.  If you've got the time and need a highly portable antenna for restricted areas or for portable use, try Peter's magnetic loop antenna.
