Practical Ideas for Portable Magnetic Loop Antennas

Magnetic loop antennas are becoming popular today because they can be very efficient for their size, do not need radials (even though most designs are vertically polarized), have useful takeoff angles, and can be easily rotated to peak or null a signal. Here’s how I designed a convenient setup for myself.

Electronics Padawans

As the Jedi Padawans demonstrate in Star Wars, acquiring the first 80% of knowledge and skills may take a few weeks or months, but getting a handle on the remaining 20% usually takes years of study and practice under the leadership of a master.

Easing Into STEM

I’m often asked what the best way is to support STEM (Science, Technology, Engineering, and Math) education with electronics. At the high school level, as soon as I start talking about Arduino boards and sensors, teachers tend to run away. It’s intimidating to set up an electronics workshop from scratch. Think of all the necessary infrastructure that needs to be constructed — from multimeters and soldering irons to parts bins — and the components to fill them.

Setting Up a Test Bench

I can hardly imagine an electronics enthusiast without some sort of test bench. This can be as simple as a folding table and a couple of hand tools, along with a cheap DMM (Digital MultiMeter). Or, it can be as elaborate as a spare room just loaded with TE and a full complement of tools and accessories to go with it.
