Master the 80m–10m bands with the classic W3DZZ trapped dipole. This guide explores the technical design, trap construction, and real-world SWR performance of this legendary multi-band antenna. Perfect for hams seeking a compact, high-performance HF solution without a complex tuner
The inverted rhombic antenna boasts a distinctive half-rhombic configuration. Its directivity focuses toward the terminated end, enhancing signal precision. Developed by Bruce, it demands a non-conductive mast for optimal performance. This design delivers significant gain across the 50 to 70MHz bands. A non-inductive terminating resistor is essential, tailored to the RF power delivered. For SSB […]
Can’t fit a full-sized 80-meter dipole in your backyard? Or maybe you’re tired of the high noise floor of a vertical? It’s time to look at the Half-Loop. This “open-loop” design provides a fantastic balance between the quiet reception of a loop and the simplicity of a wire antenna.
In this project, we explore a multiband Half-Loop configuration that covers everything from 80 meters down to 15 meters. We’ll discuss the radiation pattern, the importance of a good ground or counterpoise, and how to use a simple tuner to jump between bands. If you’re looking for a “stealthy” antenna that punches above its weight on the low bands, this build is for you. Let’s get that wire in the air!
