The RB-220 20m beam’s DX performance is surprisingly good even when it is operated as low as ½ wavelength above ground. Its Light weight and short boom make it perfect for both normal and limited installation environments, field day, and especially DXpeditions.
Don’t let its small size fool you. This little beam will outperform yagis of twice the boom length and greater, and you will hear the weak ones even better due to its low noise characteristics. Its supergain performance is backed by a money-back guarantee.
