What is the OptimizIR?:
The OptimizIR includes all of the standard features that the SDA 100 offers 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 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.
Attaches to base of the BigIR vertical, expanding coverage to the 80m/60m bands. Power limit of 1kW for 80m/60m, 3kW on 40-6m. Additional 4 conductor cable required when adding this option Click Here.
SteppIR Verticals are the only true ¼ wave continuous coverage antennas available for the HF bands.
The SteppIR technology has had a profound impact on improving vertical antenna performance over that of traditional designs – there is no substitute for having a true 1/4 wave vertical on every frequency within the coverage range, without having to “trick” the antenna into being resonant. Being able to adjust the length of the element allows the SteppIR vertical to be mounted nearly anywhere and still provide a good match to your transceiver. As with all ¼ wave verticals, ultimate performance depends a good radial system. SteppIR verticals can be ground mounted or elevated above ground.
