The XFORM 4:1 Transformer Module is the first release in the REZ XFORM System, expanding the capability of the Scout XF (XFORM Ready) Base beyond resonant antennas. Engineered with precision-wound cores, careful insertion loss analysis, and thermal testing, the XFORM 4:1 delivers maximum efficiency in a compact, field-ready package.
When paired with the Scout XF, the XFORM 4:1 enables a range of non-resonant antenna configurations, including:
Delta loops for balanced, versatile performance
Rybakov-style verticals for multi-band operation
The XFORM 4:1 is fully modular and rugged, built from weather-resistant materials to match the reliability of the Scout system. And while it was designed for the new Scout XF, it’s also backward compatible with the original Scout base—a simple jumper connection brings XFORM capability to legacy Scout users.
Together with the Scout XF, the XFORM 4:1 transforms your kit into a multi-band, multi-mode platform that adapts to any operating environment.
