Construction details and use are outside the scope of this overview. Ideally the wire-needs to be at least half a wavelength long and for MW that means > 100 metres (ideally you need 200-500 metres). These antenna configurations normally receive in one direction, but the BevFlex-4X allows you to instantly switch to the reverse direction. While Beverage antennas have excellent directivity, because they are close to lossy Earth, they do not produce absolute gain; their gain is typically from −20 to −10 dBi making it not very good as compared to other antennas. They are used in wireless power transmission systems that transmit power by radio waves. I just can't figure out why; I am using a DX Engineering matching transformer that is grounded with four ground rods and two long radials running at 45 degrees off from the antenna itself, while the end of the Beverage is terminated in 470 ohms and attached to two ground rods. 1.
