RF.Guru Incredible Lab Newsletter – Issue #3
Where physics and antennas meet reality (and sarcasm).
Faraday Rotation: The Invisible Force That Shapes Your HF Reception
Understand why your signal is vanishing, shifting, or fading — and how to receive in LHCP or RHCP to beat it.
RF in the Shack? It’s Skin Effect, Not Common Mode
Stop blaming CMC for everything. Here's why your coax shield is really betraying you.
The Hidden Truth About the Counterpoise: It’s Not What You Think
Spoiler: your “counterpoise” might just be a floating mess. Here’s how to fix it.
The SWR Myth: The Story of the Lost Power That Isn’t Really Lost
High SWR doesn’t always mean lost power — here’s why it’s more about reflections, not waste.
NextGen Non-Resonant Traps: Engineering Performance Through Frequency, Means, and Symmetry
Traps aren’t black magic. They’re engineered solutions. Here’s how to design them the right way.
