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.
