Simple Ham Radio Antennas--100 watt 7 MHz magnetic loop for units and apartments> Post #632.


If you're having troble viewing this video, please insert this address into your browser search box: https://youtu.be/ CU_RnLpZ9gw. Here's another antenna idea for those operating in deed restricted areas, such as HOAs and CC&Rs.  In this video, Peter (VK3YE) shows us how to make a 100 watt, 7 MHz magnetic loop antenna suitable for both home and portable operation. According to Peter, "There are no hard to get parts or complex workshop skills required to build this antenna.  Instead of an expensive vacuum variable capacitor, the antenna is brought into resonance with a length of RG-213 coax (approximately 1.85 meters/6.06-feet) for a 3 m/9.84-feet circumference 7 MHz loop."  Peter adds that "The sliding capacitor can be approximately 6 X 8 cm/2.36 X 3.14 inches." Be careful where you mount this antenna, because hazardous voltages can occur on the capacitor during transmit.  Peter says he has good results with this small, portable magnetic loop antenna.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free email subscription or by tapping into the blog RSS feed.
