Unlock peak performance for your radio with the ATU-130 — a powerhouse automatic antenna tuner designed for ham radio enthusiasts, preppers, and field operators. Whether you’re running FT8 at home, chasing DXpeditions, or setting up emergency comms in remote areas, its advanced PIC chip and 12.4μH inductance system deliver lightning-fast SWR matching across 1.8–50MHz.

Crafted for rugged use, the aluminum alloy body stays cool even during marathon SSB sessions (up to 200W), while 4 large magnetic ring inductors and UHF connectors handle high-SWR scenarios effortlessly. The crisp OLED display keeps you informed on power output and SWR, so you can adjust safely—no guesswork needed.

Why pros love it:

Field-Ready Portability: Smaller than a textbook, it slips into backpacks for SOTA (Summits on the Air) adventures or mobile setups.

Fail-Safe Protection: Relays and capacitors prevent burnout during high-load modes like FM or CW.

DIY Flexibility: Tune “ugly” antennas (e.g., fence wires, rain gutters) into efficient radiators for improvised stations.
