Quest for the Best Mag Loop Antenna

This video explores the design and construction details of small loop (Mag Loop) antennas.

Here is a link to Part 2 of this video.

Here are links to 2 must see videos that I discovered after publishing this video.
   • Small Tuned Loop Radiation Direction  
I wasted a lot of time trying to duplicate the results shown in this video. I built a loop antenna for the 2M band and rotated it manually. I could not detect any directionality with a passive field strength meter. All I could show was that the far field was horizontally polarized.

For our metric friends (wish the U.S. was metric) here are conversion factors for the "inch" and the "foot".
1.0 inch = 2.54cm = 25.4mm
1.0 foot = 0.3048M = 30.48cm
