ATU-130 HF Tuner, 200W Micro Shortwave Automatic, 1.8-50MHz, 10-15VDC, OLED Display, Wide Frequency & Power Compatibility, Portable for Ham Radio Mobile

Specification: Item Type: Automatic Antenna Tuner Model: ATU-130 Material: Aluminum Alloy Power Supply Voltage Range: 10-15VDC (+in the center) Maximum Current Consumption: 500mA Maximum Working Power: 150W Starting Tuning Minimum Power: 5W Minimum Measurable Power: 0.1W Measurement Accuracy Up to 10W Power: 0.1W Measurement Accuracy Greater Than 10W Power: 1W Maximum Installed Inductance: 8.53μH Minimum Installation Inductancee: 0.05μH Micro Automatic Antenna Tuner Features: Has the function of power meter standing wave meter (according to BYPASS, straight through mode, one horizontal line in the middle of the screen, the test value is approximate, and the accuracy is lower than that of professional ​​ meter, for reference). PIC18F2520, MCU (quicker). Short wave machine automatic antenna tuner The third edition adopts the design of 4 large magnetic ring​​​ inductors, which generates less heat than the original edition. HF32, 10A, HF33, 5A relays are used. How to Use: 1. Connect the power cord 11‑14VDC power supply. 2. Connect the shortwave machine to the IN RF line of the automatic antenna tuner. 3. Connect the grounding wire. 4. The antenna is connected to the antenna antenna (M socket, or fast socket), AM, FM, CW, small power 5‑15w, and can be tuned well (within swr1.5) to use large power. 5. If you need to do it manually, you can press auto, and the dot in the middle of the screen LC disappears, which is the manual mode. Press again to switch to automatic mode. 6. In special cases, press tune to reset and LC combination to reset. packing list: 1 x Antenna Tuner 1 x Cable 1 x Accessory

• Portable Aluminum Alloy Housing: The lightweight yet durable aluminum alloy shell offers excellent heat dissipation and erosion resistance. With compact dimensions (155x88x38mm) and weighing only 0.5kg, it's ideal for base stations, mobile installations, and field operations.
• Fully Automatic Tuning & Clear OLED Display: Featuring advanced PIC microcontroller technology, the tuner automatically initiates tuning when transmission is detected—no control cables needed. The bright organic light-emitting diode (OLED) display provides clear real-time feedback on tuning status and power metrics.
• Multi-Function & User-Friendly Operation: Incorporates power meter and SWR measurement functions in bypass mode. Powered by 10-15VDC (center-positive), it consumes minimal current (≤500mA). Includes safety recommendations for sustained operation and supports quick tuning with most HF transceivers.
• Wide Frequency & Power Compatibility: This compact automatic antenna tuner operates across the full 1.8-50MHz shortwave spectrum, handling up to 200W PEP (SSB) and 100W continuous power (CW/FT8/FM). It efficiently matches impedance from 5Ω to 1.2kΩ, making it compatible with long wires, dipoles, verticals, and end-fed antennas.
• Robust Components: Built with high-voltage SMD capacitors, 4 large magnetic ring inductors, and industrial-grade relays (HF32/HF33). The 12.4μH total inductance and thicker wire windings ensure superior heat resistance and stable operation under high loads.
