DB18 Yagi Antenna, 40m-6m Package
DB18 Yagi antenna uses loop elements for 30 and 40M performance.
The DB18 and DB18E are the most popular antennas in the DB line, due to their performance vs. size profile. The loop elements used for 40 and 30m are 40% shorter than a full size element would be, with very little sacrifice in performance (-0.4dB).
The DB18 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 (standard on DB18) for effortless tuning.
The only difference between the DB18 and the DB18E is on 30m – the DB18 has two elements on 30m, making it a wide spaced high gain dipole with very little front to rear. The DB18E has 3 elements on 30m, making it an optimally spaced Yagi with solid gain and excellent front-to-rear ratios.
