These amazing short-boom beams will outperform any yagi of equal boom length. Low noise characteristics allows you hear the weaker signals, and a narrower elevation beam-width gives excellent performance at heights as low as ½ wavelength, as well as offering superior DX performance. Here is the perfect antenna solution if height or space restrictions are preventing you from making the most of your hobby.
