Background For many radio applications, antenna operation at resonance across multiple frequency bands is highly desirable and has been the holy grail for many decades. The Switched Multi-Band Antenna (SMBA) is designed to operate over multiple bands at resonance and...

For many of us, living in an HOA-managed neighborhood is a given. There are typically HOA restrictions on antennas – typically No Antennas in the newer neighborhoods. Now I’m not going to debate the pros/cons or rights/wrongs about HOA. The main purpose of...

In July, my Spiderbeam mast was sideswiped by the winds from a thunderstorm that took out the mast and put an abrupt end to my Spiderbeam – a great antenna I’ve enjoyed for several years. Someday I plan to replace the Spiderbeam once I have a location I...

I recently had a trip to Bear Lake in Idaho planned and wanted to do some portable operation, so I decided to give the CrankIR a try. The heat in Texas becomes tiresome, so getting away from it further north is nice in the summer, and a great opportunity to experiment...

As I just shared on our Antenna Design slack channel, I was fortunate enough to pass the Extra exam yesterday. I had some top-notch instructors – Skip Ferguson/K5LLR and Keith Dutson/NM5G, who invested their time with a bunch of us over two weekends to help pull...
