Simple Ham Radio Antennas--100 watt 7 MHz magnetic loop for units and apartments. Post #809.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/Cv_RnLpZ9gw. Another great video tutorial from Peter Parker (VK3YE).  In this program, Peter describes and demonstrates a 100 watt 7 MHz magnetic loop antenna suitable for apartment, portable, and emergency use.  Peter says "there are no hard to get parts or complex workshop skills needed to build this antenna."  Rather than use expensive air variable capacitors to bring the antenna into resonance, Peter uses a length of RG-213 coaxial cable for the task (1.85 meters/6.06 feet). The sliding capacitors measure approximately 6 cm x 8 cm (2.3 inches x 3.14 inches). For the latest amateur radio news and events, please check out the blog sidebars.

If you're having trouble viewing this video, please enter this title link into your browser search box: https://youtu.be/Cv_RnLpZ9gw.  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.

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 a
