Wire Antennas 160 meter to 70 cm: Concepts, Construction and On the Air

Bob Glorioso, W1IS & Bob Rose, KC1DSQ

This is a slightly different antenna book that not only attempts to help you understand the theory associated with each design presented. BUT, we also build and put on the air where possible all the antennas. This allows us to show you the details for building and deploying these antenna designs yourself.

The approach we have taken introduces the basic antenna upon which all other antennas depend, the Dipole and some fundamentals that are the tools needed to understand more deeply antenna principles.

Not wanting to drown the reader who wants to BUILD NOW with technical material, Chapters 2 and 3 should be skimmed so you to pick up some of the vocabulary and know where to go as you get deeper into making your antennas work better.

Thus, we try to give you an understanding of the foibles of each antenna described throughout the book in Chapter 6 on End Effect, Chapter 7 that goes deeper into dipoles, and Chapter 9 on the design constraints of multi-band harmonic antennas.

Next Chapter 11 builds on these concepts as they are applied to a simple dual-band 40-meter, 15-meter dipole.

Going further we extend the principles in previous chapters to Off Center Fed antennas in Chapter 12 and End Fed Antennas in Chapter 13 where we have straight wire designs suitable for Attics. POTA and SOTA operations.

Small spaces are a problem many hams have so we describe, build and test C-Poles, just another dipole configuration, for 40-meters as well as a dual band 40-meter. 20-meter version. These can be deployed both horizontally and vertically, suspended from a tree branch or house eave.

The next two chapters explore and present antennas that have gain over a dipole, Chapter 15, the longest chapter in this book, explores, mostly portable, wire and wood beams for 40-meters, a tri-band two element beam for 20, 15 and 10-meters, high gain phased dipoles for 20-6 meters, a Moxon beam and unique 70cm beams both linear and circularly polarized.

Chapter 16 deals with stacking antennas for inexpensive power doubling with horizontal stacks for 10-meters and 6-meters as well as a vertical colinear for o2-meter.

Vertical antennas are explored in Chapter 17 describing both on the ground and over the ground verticals for 160-meters, 80-meters and 40-meters. Versions called an “Inverted L” are alternatives for those with limited space and low frequency ambitions.

The Loop antenna, Chapter 18, is another universal configuration for antennas for AM radios, Direction Finding, HF receiving antennas to transmitting antennas for QRP to QRO. Depending on how they are fed, they can be horizontal or vertically polarized. Many of these are described in Chapter 18.

The final Chapter 19, contains wit and wisdoms that are valuable or just plain amusing for work on antennas.  This chapter can serve as a reference as you plow through the design of a new antenna or are struggling to deploy a new antenna.

205 pages, 250+ Diagrams and Photos to help you build your own.
