The Complete Ham Radio Antenna Build Guide - Volume 1: HF Wire & Loop Antennas
Every antenna journey in amateur radio starts the same place: a length of wire, a feedpoint, and the question of how to get it up in the air. Volume 1 of the Complete Ham Radio Antenna Build Guide is that starting point - and it takes wire and loop antennas further than most operators ever realize they can go. This is the foundational volume of a 5-volume series that takes you from your first dipole to advanced directional arrays, and it's built to get you on the air with a working antenna as quickly and correctly as possible.
The book opens with the half-wave dipole, the antenna every ham eventually builds and the one every other wire antenna in this volume is measured against. You'll learn not just how to cut one to length, but why it behaves the way it does - feedpoint impedance, radiation pattern, and how height above ground changes everything about how it performs. From there, the doublet gets its own treatment as the multiband cousin of the dipole, fed with ladder line and a tuner to work bands a single-length dipole never could.
End-fed half-wave (EFHW) antennas get a full, practical build-out, including the matching transformer construction that makes them work - the 49:1 unun windings, core selection, and the counterpoise considerations that trip up so many first-time builders. Off-center-fed dipoles (OCFDs) follow, along with a clear explanation of why the offset feedpoint changes the impedance and how that translates into the transformer ratio you need. The venerable G5RV gets its own chapter too, including an honest look at what it does well, where it compromises, and how to build one that actually performs the way its reputation suggests.
The second half of the volume moves into loop antennas - a category many antenna books treat as an afterthought, but one that gets real depth here. Magnetic loop antennas are covered from theory through construction, including the high-Q tuning capacitor considerations and coupling loop design that make a small transmitting loop actually work rather than just look impressive. Full-wave loops and delta loops follow, with construction guidance for both horizontal and vertical orientations and a clear comparison of how their radiation patterns differ from a simple dipole at the same height. The volume closes with receiving loops - small, often overlooked antennas that can dramatically improve your ability to pull weak signals out of the noise on the lower HF bands, especially valuable for anyone dealing with a noisy urban or suburban RF environment.
Every antenna in this book follows the same structure: a clear explanation of the theory behind the design, a complete materials list, step-by-step construction instructions, a dimensions table you can adapt to your target frequency, and a tuning and SWR verification process using a NanoVNA or antenna analyzer. This isn't a book of antenna theory to read and set aside - it's a build guide meant to sit next to you in the workshop while you're winding a balun or cutting wire to length. Interactive online calculators at hamradiobase.com/ham-radio-antenna-build-guides complement every chapter, letting you enter your exact target frequency and get real dimensions rather than scaling a table built for a different band.
Whether you're a brand-new operator building your first dipole, a seasoned ham looking to add a magnetic loop to a restricted lot, or anyone in between who wants to actually understand what's happening at the feedpoint instead of just copying a formula, Volume 1 gives you the foundation the rest of the series builds on - and gets you making contacts with a wire antenna you built and understand yourself.

Descripción de la tienda
We first started out as “The Paperback Exchange,” a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become “PBShop.” This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.…
