The Icom AH730 HF/50 MHz (1.8-54MHz) Automatic Antenna Tuner is a professional-grade antenna built for demanding two-way radio environments. Highlights include wide Range Matching and intelligent High-Speed Auto-Tuning.
Key Features
- Wide Range Matching: Automatically tunes a massive spectral layout from 1.8 MHz through 54 MHz when paired with an antenna element 7 meters or longer.
- Intelligent High-Speed Auto-Tuning: Analyzes more than one million LC configurations to lock in a safe match within 2 to 3 seconds.
- 45 Frequency Memory Slots: Retains previous matching paths inside on-board memory arrays to perform rapid 1-second tuning cycles on recalled channels.
- Ultra-Low Tuning Radiation: Emits an extremely low 0.3W RF signature during active matching cycles to minimize spectral interference with adjacent stations.
