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.

Matching Waves, VSWR at work - When the radiation resistance (voltage to current ratio) of an antenna is the same value as the characteristic impedance of the transmission line (voltage to current ratio in the line), all of the electrical energy transmitted down the line is taken by the antenna and radiated into space in the form of a radio wave.

PolarPlot - Freeware antenna software that lets you see what the polar diagram of your rotatable beam actually looks like where it is operating. With PolarPlot you can measure the polar diagram of the antenna and check for abnormalities - compare plots taken before and after changes to the design or location - check the -3dB beamwidth - look at the front to back ratio - see the size and position of the sidelobes.
