The pileup buster

The DX performance of our RB-506 is awesome even when it is operated as low as 2 wavelengths above ground. This 5 element wide spaced mono-band beam is easily supported by a medium duty tower, and turned with a medium duty rotor. When mounted at 60 to 75 ft. or higher it is the ultimate contest beam -- and truly a force to be reckoned with. It will compete with yagis with much longer boom lengths, and you'll hear the weak ones better due to its low noise characteristics.
