Description

Description

The DB18E Yagi antenna utilizes folded dipole technology for 30 and 40 meter performance.

There are 3 looped elements on the antenna. On 40 meters, two loop elements are active and on 30 meters through 6 meters all three elements are active. The DB18E 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 singular difference between the DB18E and DB18 are the number of active elements on 30m – on the DB18E there are 3 active elements on 30m and on the DB18 there are 2 active elements on 30m.

  • Controller options:


The OptimizIR 2.0 Controller includes all of the standard features that the original SDA 100 offered and in addition offers a larger full-color display, enhanced GUI, can be used on ANY SteppIR antenna, and has the capability for the user to import created antenna models. Since this controller has the memory to store extra antenna models, SteppIR has gone ahead and modeled some cool yagi antennas including a max gain, max f/r, and wide beam antenna. These come stock on the OptimizIR 2.0 for use straight away, and are viewable on a full color “power band” so it is easy and intuitive to visually determine the gain/FR weighting on the antenna model. The OptimizIR 2.0 also has the capability for full remote control as an additional option upgrade (more details and cost of upgrade to be released soon!).
