With the DB11, you don’t have to give up performance to fit the antenna into a small space!
The DB11 is the smallest of our Yagi antennas that uses loop technology. This is a distinctive advantage, allowing for a 40% smaller size platform with excellent performance. The DB11 uses an integral coax switch to select which one of the three elements are driven to give equal performance in forward and reverse directions. The control of the Antenna and Coax switch is integrated into the SDA100 controller for effortless tuning. The DB11 is our only antenna without the optional 6m passive element kit – the spacing of the 3 elements turns out to be ideal for 6m as well.
With two active elements on 20m and three active elements above 20m, an average of 7 DB of gain, and 20 DB front/rear ratio is obtained on each band.
