REZ Antenna Systems XFORM 4:1 UNUN

The REZ Antenna Systems XFORM 4:1 UNUN is a modular impedance-matching system designed for the Scout system, expanding its capabilities beyond traditional quarter-wave verticals and half-wave dipoles. It integrates seamlessly with the Scout XF base and supports legacy Scout bases via a jumper connection. The XFORM enables over 30 potential antenna deployment options when combined with future 9:1 and 49:1 transformer modules, which are currently in development.

Built for durability, the XFORM features CNC-machined 6061 aluminum, an acetal polymer body, and stainless steel hardware. Its gasket-sealed design ensures reliable performance in harsh weather conditions. The unit handles up to 200 watts PEP SSB and 75 watts digital (50% duty cycle) and measures 5.5 inches in length with a maximum diameter of 2.5 inches.

Each core is precisely wound and tested for thermal stability and minimal insertion loss, delivering efficient signal transfer and cooler operation underload. The XFORM requires a Scout base for use, making it an essential upgrade for operators seeking maximum versatility and performance in portable HF antenna systems.

Key Features:

- Modular Design and Broad Compatibility: Swappable transformer modules expand the Scout system for multi-band antenna configurations, and Integrates with Scout XF base; legacy Scout bases supported via jumper for seamless system upgrades
