Welcome to anviga.tech, the home of carefully crafted, high-performance antennas and HF systems designed for radio amateurs who value efficiency, craftsmanship, and innovation.

My name is Antonio Ansanelli, and since 1969 I’ve nurtured a deep passion for amateur radio — especially the art and science of building antennas and accessories with my own hands. Over decades, I discovered that the true spirit of amateur radio lies in home-construction: the ability to transform theoretical ideas into real, functional, and efficient devices.

At anviga.tech we stand for:

• Technical excellence: every project begins with careful calculations, magnetic-field simulations, resonance tests, and efficiency measurements.
• Quality and durability: we select premium materials — such as anodized aluminum flat bar (40×2 mm) — and precise mechanical construction to ensure stability, longevity, and reliable operation.
• Compactness and performance: our designs are optimized for limited spaces, providing high performance even where room is scarce.
• Hands-on craftsmanship: building antennas is not only technical work, but a creative and manual process — blending knowledge, skills, and curiosity.
• Passion for experimentation: for us, every antenna is a journey — a challenge to improve, test, and refine.

One of our flagship developments is a dual-parallel magnetic loop antenna for the 10–21 MHz HF band. After three years of design, testing and refinement, the result is a compact, elegant, efficient antenna — suitable for both portable and fixed-station use — that delivers stable resonance and excellent radiation efficiency across the entire band.

But anviga.tech is more than just antenna building. This project is born from a conviction: that the amateur-radio community thrives on sharing knowledge, experimentation and collaboration. By documenting our design approach, construction choices and results, we hope to inspire other radio amateurs to explore, experiment, and innovate.

If you are looking for a custom-built, high-performance HF antenna, or if you simply share our curiosity for RF design and build techniques, we invite you to explore our publications and contact us for a tailored quote.

Thank you for visiting — and welcome to a community where ideas become antennas, and antennas become performance.
