The REZ XFORM 9:1 is a compact impedance-matching module designed for portable non-resonant wire antenna configurations across multiple HF bands. Built around the modular XFORM platform, it provides the matching interface for deployments where broad operating flexibility and adaptable field geometry are more useful than a single-band resonant antenna.

The XFORM 9:1 supports multiple wire configurations, including flat-top, sloper, and Inverted-L Sloper arrangements, allowing the antenna to adapt to available supports, operating space, and site conditions.
