DeepVNA Master Class: Your Practical Guide to the Vector Analyzer
Introduction: When a Transceiver Is Not Enough
Every radio amateur knows – a good antenna is half a transceiver. But how do we know if it is really working at its maximum, especially when we are in the field in field conditions (SOTA/POTA)? This is where the vector analyzer comes to the rescue. NanoVNA and its older brothers, such as DeepVNA 101, changed the rules of the game, but they come with one serious problem – the official instructions are often “dry”, incomplete and written in an incomprehensible technical language, which is sometimes only Chinese.
That’s how the idea for this book was born. After I was often asked how exactly I use my DeepVNA to tune JPC-12 or End-Fed antennas, I decided to turn my experience into a structured, practical guide. “DeepVNA Master Class” is not just a translation of the official operating instructions – it is a “Master Class” born from hundreds of measurements and practical experience in the field.
Who is this book for?
For beginners: If you have just bought a DeepVNA (NanoVNA or similar device) and are wondering what all those graphs it draws mean, this book will take you step by step in understandable language to learn them. You will learn why calibration is critical and how not to be “tricked” by your own device.
For advanced users: Here you will find details about the Smith chart (without unnecessary formulas), TDR diagnostics for finding defects in cables and how to use PC software (NanoVNA Saver) for precise tuning of multi-band antennas.
Key highlights in the “DeepVNA Master Class”
The language of the radio amateur: Forget complex mathematical formulas. Everything is explained simply, with clear examples from practice.
Practical scenarios: Tuning of dipoles, vertical antennas (like Rybakov), end-fed systems and filters.
Practical recipes: Specific data for popular antennas (coils and windings of JPC-12, lengths for End-Fed).
The Hidden Dangers: How to calibrate, where the power setting is located, and what to do if the touchscreen stops working.
PC Software: A quick guide to the NanoVNA Saver and how it helps with End-Fed antennas and other multiband antennas.
This book is the perfect complement to my previous FTDX10 and FTX-1F “Master Classes,” closing the loop between transceiver and antenna.
