With a wide working range of 1.8-55 MHz, it covers most amateur radio HF bands and adapts to many antennas for reliable transmitting and receiving. The tuner houses a set of 7 capacitors and 7 inductors, enabling the largest configuration to achieve effective tuning across the band and help you eliminate SWR mismatches quickly. Constructed from durable aluminum alloy in a sleek black finish, it is wear-resistant and reliable for everyday use.\u003c\/p\u003e \u003cp\u003eKey features include a built-in 1500mAh lithium battery (3.7V) and USB Type-C charging, so you can tune on the go without constant power. The 0.91-inch OLED display shows tuning status, SWR, and power readings clearly, making operation straightforward even in field conditions. Automatic tuning means no control wires or manual tweaks are needed—just connect your radio, ATU, and antenna, and press tune.\u003c\/p\u003e \u003cp\u003eOne-button operation keeps things simple: turn on\/off with a single press, making it ideal for quick setup and portable use. The ATU100 supports up to 100W maximum working power and can measure up to 150W, giving you solid performance for most station setups. A typical operating voltage is +12V (DC 10-15V, 13.8V).\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEasy, automatic tuning: no hands-on tuning or control cables needed, saving time and reducing guesswork in real-time DX or field days.\u003c\/li\u003e\n\u003cli\u003ePortable power for field use: built-in 1500mAh battery and USB-C recharge support mobile setups and emergency operations.\u003c\/li\u003e\n\u003cli\u003ePractical tuning guidance: for first use, set radio output power to 20-30W; tune in frequency modulation mode and observe SWR\/PWR on the ATU display; if SWR is above 2.0 during transmission, adjust or reduce power; when tuning completes and SWR is under 2.0, you can use up to 100W.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eName: ATU100 Tuner\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminum alloy\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eDisplay: 0.91 inch OLED\u003c\/li\u003e\n\u003cli\u003eBattery: Built-in lithium battery, 3.7V, 1500mAh (included)\u003c\/li\u003e\n\u003cli\u003eCharge: USB Type-C\u003c\/li\u003e\n\u003cli\u003eVoltage: Typical +12V (DC 10-15V, 13.8V)\u003c\/li\u003e\n\u003cli\u003eWorking frequency: 1.8-55 MHz\u003c\/li\u003e\n\u003cli\u003eMaximum current consumption: 400 mA\u003c\/li\u003e\n\u003cli\u003eMaximum working power: 100W\u003c\/li\u003e\n\u003cli\u003eMaximum possible measurement power: 150W\u003c\/li\u003e\n\u003cli\u003eMinimum power to start tuning: 5W\u003c\/li\u003e\n\u003cli\u003eMinimum possible measurement power: 0.1W\u003c\/li\u003e\n\u003cli\u003eMeasurement step for power up to 10W: 0.1W\u003c\/li\u003e\n\u003cli\u003eMeasurement step with power higher than 10W: 1W\u003c\/li\u003e\n\u003cli\u003ePower measurement accuracy: 10\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eATU100 Tuner\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWarnings \u0026amp; Reminders\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFor the first use, set the radio or power amplifier output between 20-30W to protect the tuner during tuning.\u003c\/li\u003e\n\u003cli\u003eIf the SWR display in transmitting state is greater than 2.0, the antenna may be detuned; reduce power or adjust tuning.\u003c\/li\u003e\n\u003cli\u003eAfter tuning, ensure SWR is less than 2.0 before transmitting; do not exceed 30W if SWR remains high during initial tests to avoid damage.\u003c\/li\u003e\n\u003cli\u003eWhen tuning supports up to 100W, stay within safe operating limits for both the tuner and your radio equipment.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eProviding quality and trusted service since 2002 at intercyprus.com.\u003c\/p\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cp\u003ePlease note: All electronic and mechanical equipment, devices and machines sold to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e","brand":"InterCyprus","offers":[{"title":"ATU-100-0A","offer_id":51478311010646,"sku":"1005005562777075-ATU-100-0A","price":94.82,"currency_code":"EUR","in_stock":false},{"title":"ATU-10-0A","offer_id":51478311043414,"sku":"1005005562777075-ATU-10-0A","price":99.82,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/S07966d36c3034287895c2858784f7f91m.webp?v=1759509694","url":"https:\/\/www.intercyprus.com\/de\/products\/atu-100-0a-1-8-55mhz-mini-automatic-antenna-tuner-aluminum-alloy-outcase-with-1500mah-battery-oled-display-atu-antenna-tuner","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
