The REZ XFORM 4:1 is a compact broadband matching module designed to expand the Scout and XFORM platforms into non-resonant vertical, wire, loop, and other field-configurable HF antenna arrangements.

Rather than being tied to a single resonant radiator or band-specific loading network, the XFORM 4:1 provides a broadband matching interface for compatible antenna configurations where a 4:1 impedance transformation is appropriate. This gives operators another way to adapt the system around available wire, radiator length, support geometry, and operating requirements.
