• Beverage Antennas - So you want to build a Beverage Antenna. This article offers insights on building a two-wire Beverage antenna for better reception. Key points include using long wire (at least a wavelength, ideally two), keeping it straight and away from vertical conductors, and sloping ends for noise reduction. The author recommends copper clad wire and mentions transformer design considerations for later discussion.
