Magnetic Loop Compendium – Summary of Work
For the past five years I have experimented with magnetic loop antennas. I thought it was time to publish a magnetic loop compendium of my work, complete with links to all articles. Read more
3D Printed Solutions for Magnetic Loop Antenna
Have you ever tried to attach a nut inside a small diameter tube? How about a one-of-a-kind mounting bracket? 3D printed solutions are magic. Read more
Painting PEX Pipe – Options and Approaches
Painting PEX pipe gives your orange plastic loop antenna an aluminum appearance. I experimented with Krylon Fusion as well as ordinary 100% acrylic latex. Read more
Simpler Lighter PEX Wideband Loop
This week I created a simpler lighter PEX wideband loop. It has half the weight and better stability than my first version. Looks better, too. Read more
Loop Construction Modular Approach
Since the start, I have taken a loop construction modular approach which makes it easy to experiment with different ideas. Read more
Mostly Plastic Wideband Receiving Loop
With aluminum core PEX, we have created a mostly plastic wideband receiving loop that should survive Calgary’s weather extremes. Only time will tell how well it holds up. Read more
