SteppIR Verticals are the only true ¼ wave continuous coverage antennas available for the HF bands.
Introducing the StealthIR flagpole antenna! This is the new performance standard for users in HOA restrictive environments, or for those that have neighbors that are not as appreciative of the beauty of a resonant, optimized vertical antenna system!
The StealthIR vertical is a 20m-6m antenna, hidden inside an attractive flagpole with base. Optional 80/60/40/30m or 40/30m coil is available and fits underneath the rock base. The antenna currently is only available for use utilizing ground radials.
The system includes a two-piece non-conductive “flagpole”, which is flexible enough to take high winds, but sturdy enough to pass as a high-quality flag pole. A flagpole mounting assembly, as well as the fake rock base, are included with the system. The US Flag is optional, and any 3 ft x 5 ft flag will fit if you would like to provide your own flag.
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 on a good radial system.
