  • Beverage Antennas for Low-Band, Weak-Signal Research

    To set the stage for future data collection and research opportunities, one of our inaugural projects was a series of Beverage antennas for long-wave, low-frequency bands (receive only).  Why Beverage antennas? They’re easy and quick to execute. Since they don’t need to be high off the ground, we can mount them on a few 4x4s…

  • Antennas in Various Stages of Operation on Our Site

    As of January 2026, we have several antenna setups that are in various stages of operation or repair on our site. Here’s an overview. The start of the Giga Loop A full-wave 630m loop at varying heights ranging from 10 to 100ft off the ground. In practice, the feedpoint impedance is way off from the…

  • A Back-to-Basics WSPR Beacon Setup (It Reached Tasmania!)

    For me, Amateur Radio is about designing and building equipment, experimenting, and learning. I have done so for/on almost every amateur frequency, from 630m to X-band. Rag chews or contesting do not speak to me much. My antennas are mostly omnidirectional, simple, and resonant, including a full-wavelength loop on 472 kHz. However, reality forces me to settle for a…
