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.
