Most Hams Get Resonance Wrong—Do You?
Most amateur radio operators learn that a low SWR means a good antenna and a high SWR means a bad one. But what if that isn't the whole story?
In this episode of Brew & Activate, we're tackling one of the biggest myths in amateur radio: the idea that resonance and SWR are the same thing.
We'll break down what resonance actually means, why reactance (X) is often more important than SWR when tuning an antenna, and how an antenna can be perfectly resonant while still showing a 2:1 SWR. We'll also explore resistance (R), impedance matching, feedpoint impedance, and how to read antenna analyzer measurements in a way that helps you make better decisions in the field.
Whether you're deploying antennas for Parks on the Air (POTA), chasing DX, experimenting with end-fed wires, or simply trying to understand what your analyzer is telling you, this discussion will change the way you look at antenna tuning.
In This Episode
What resonance really means
Why X = 0 matters
The difference between resonance and matching
Why low SWR does not always mean a good antenna
How to interpret R and X on your analyzer
Real-world examples from portable operations
Common SWR myths many hams still believe

Do you agree that SWR is one of the most misunderstood measurements in amateur radio?
Have you ever chased a perfect SWR only to discover it didn't improve your signal?
Drop your thoughts in the comments and continue the discussion with the Brew Crew.
