WW2Y/K2WI Beverage design - Ideas for enhanced beverage antenna performance, Single wire beverage improvements and arrays of two beverages. This article explores improving reception with Beverage antennas. It discusses single wire Beverages and their limitations. Then it compares two array configurations: broadside and end-fire. Broadside offers better front-to-side ratio but requires more space. End-fire offers better front-to-back ratio and takes less space but is trickier to implement for multiple bands. The article concludes with a 3-element end-fire design for excellent performance and explores possibilities for dual-band configurations.

Beverage Antenna Construction - Types of beverage wires, choose best supports and insulators, multiple antennas at one feedpoint, all well documented with photos and exaustive explanation. This article offers insights on building Beverage antennas for optimal reception. Key takeaways include using strong wire (copperweld or electric fence), proper termination, and a good grounding system (multiple copper rods). The author recommends maximizing antenna length and orienting it towards desired stations. For best results, utilize an antenna tuner and experiment with termination resistors.

A Reversible Beverage at ZL3IX - How do two-wire reversible direction Beverages work, an excellent document that explains fundamentals of beverage antennas. This article details the design and performance of a reversible beverage antenna. Leveraging orthogonality between common mode and differential mode currents on a 2-wire line, this antenna facilitates independent reception from both ends. While common mode signals arrive and are summed on a transformer's secondary for common mode reception, differential mode signals induce anti-phase currents, providing individual reception. Various measurements explore impedance, transmission loss, and F/B ratio, highlighting the antenna's effectiveness and areas for improvement. Notably, increasing the antenna's height significantly improved performance.
