End-Fed Antennas

About this book

The end-fed half-wave has become the favourite wire antenna for small gardens, and one of the most misunderstood. This book shows you how to build it properly, and why it works, with every design modelled before you cut a wire.

• Five complete builds: the EFHW with its 49:1 transformer, the L-match EFHW, the random wire, the Zepp and Extended Double Zepp, and portable end-feds for poles and hilltops.
• Every antenna modelled in NEC2: elevation and azimuth patterns, SWR and impedance on every band, one page per band.
• Cutting lists in metric and imperial, with step-by-step construction and tuning.
• The hidden half of every end-fed: counterpoises and common-mode chokes, explained and tested.
• Written for UK amateurs: licence power limits, the Ofcom exposure condition and planning, with safety guidance at every step.

Friendly, practical and honest about what works and what doesn't, it suits a first antenna build and an experienced builder alike.

Part of the Aerial Works series of practical antenna books for radio amateurs.
