The Southwest Antennas HF Auto-Tuner is a technology demonstrator that enables system integrators and radio OEMs to evaluate advanced HF antenna tuning technology within their own platforms and operating environments. Designed as a fully functional evaluation unit, it provides a practical way to test tuning performance, define integration requirements, and collaborate on the development of application-specific HF tuning solutions.
Covering the 1.8 MHz to 30 MHz frequency range, the compact HF Auto-Tuner uses proprietary Tune Once Technology to deliver rapid antenna matching by learning and storing successful tuning solutions for future use. The system can evaluate thousands of possible matching combinations, retain up to 512 customizable memory channels, and accelerate subsequent tuning cycles by recalling previously validated configurations. With support for tactical RF applications, SKYwave propagation, and integration-focused development programs, the HF Auto-Tuner provides a lab-ready pathway for creating optimized HF communications solutions for unmanned systems and other specialized platforms.
