Initial Wideband Loop Testing
My initial wideband loop testing shows reasonable MW and Lower HF performance, but I need to address shielding and impedance matching to prevent the CAT7 from acting as an antenna. Read more
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
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
D-Day Radio Action 75 Years On
On the 75th Anniversary of Operation Overlord, let’s remember D-Day radio action on the beaches. Read more
DIY Wideband Loop Rotator Concept
Here is a DIY wideband loop rotator concept that should work with either stepper or DC geared motors and cost less than $30 to build. Let’s take a look. Read more
Loop Rotation Options Considered
You should check out wideband loop rotation options if you plan to use the antenna for low-angle DX reception at long, medium and lower HF frequencies. What are the options? Read more
