This is post 2415 in a continuing series of simple ham radio antennas.

Thanks to Julian (OH8STN) for this excellent, informative tutorial on making a low-power magnetic loop antenna for radio amateurs.

The antenna is light weight, compact, and easy to erect and take down.  

Here are some comments from Julian:

In this video we build our own Man Portable Magnetic Loop Antenna. The video has details for two different antenna, both based on the Chameleon Magnetic Loop starter kit. Here are the details: a - 40-10M single turn, man portable loop based on the Chameleon P-LOOP. - 80, 60, 40M 2 Turn, Man Portable Magnetic Loop Antenna. Th The 80,60,4m version can be built for only those bands, or as a convertible model with a switched capacitor allowing quick conversion between 40-10M or 80-40m modes. Power handling: 10W DATA/CW or 25W SSB A page has been setup with build notes, images, WSPR Test results, Links to buy the parts for your own loop, educational resources, calculators, and everything a Starter Kit builder could need to get their own loop build off the ground.The page is still work in progress, but will be completed within a few days after the video is published. http://oh8stn.org/blog/2017/02/09/diy... multi turn loop calculator: http://people.physics.anu.edu.au/~dxt... Remember we are not trying to compare these magnetic loop antenna with full size amateur radio dipoles mounted many feet or meters in the air. Our goal is to build a practical and portable HF field antenna, which won't take lots of space, weight, which can be used with our QRP radio on the go. So the practical aspects of the loop may at times out weigh the performance benefits of other antenna designs. I really encourage you to share your your own starter kit inspired homebrew projects. If you would like me to feature your magloop on the build page, just email me a full HD image to "magloop @ my callsign dot org". - If you found this episode useful, consider dropping a buck in the tip-jar here: https://paypal.me/oh8stn/1USD 73 Julian #oh8stn - Easy to Deploy Portable Vertical Antennas: https://www.youtube.com/playlist?list... - Ham Radio with a Raspberry Pi: https://www.youtube.com/playlist?list... - Yaesu FT-891 Info & Tutorials: https://www.youtube.com/playlist?list... - DIY LiFePO4 10ah battery pack for Ham Radio: https://youtu.be/nDoQoVA0hAc - PowerFilm FM16-7200: https://www.youtube.com/playlist?list... - Ham Radio Off Grid with OH8STN https://www.youtube.com/playlist?list... - Better Power Distribution for Portable Ops https://oh8stn.org/blog/2018/11/03/be...
