It operates automatically, beginning a tuning cycle whenever SWR exceeds a preset limit — to protect its circuitry, tuning is performed at exciter power only (bypass or standby your amplifier during the tune cycle). A large bar-graph wattmeter displays forward and reverse power alongside SWR, and two antenna output connectors with 2,000 memories each allow near-instant retuning on previously used frequencies.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e600W SSB\/CW rated — suitable for use with mid-size amplifiers\u003c\/li\u003e\n\u003cli\u003eCovers 1.8–54MHz (160m–6m) continuously\u003c\/li\u003e\n\u003cli\u003e4,000 memories (2,000 per antenna) for near-instant band changing\u003c\/li\u003e\n\u003cli\u003eTwo antenna output connectors with independent memory banks\u003c\/li\u003e\n\u003cli\u003eBar-graph wattmeter: forward power, reverse power, and SWR\u003c\/li\u003e\n\u003cli\u003eTunes 6–800Ω loads (16–150Ω on 6m) — Yagis, dipoles, inverted-Vs, slopers, and coax-fed antennas\u003c\/li\u003e\n\u003cli\u003eLongwires or ladder-line fed antennas require an external balun (not included)\u003c\/li\u003e\n\u003cli\u003eOptional M-600 4.5\" analog meter available separately\u003c\/li\u003e\n\u003cli\u003eIncludes DC power cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFrequency Range: 1.8–54MHz\u003c\/li\u003e\n\u003cli\u003ePower Rating: 600W SSB\/CW (tune at exciter power only)\u003c\/li\u003e\n\u003cli\u003eLoad Range: 6–800Ω (16–150Ω on 6m)\u003c\/li\u003e\n\u003cli\u003eMemories: 4,000 (2,000 per antenna output)\u003c\/li\u003e\n\u003cli\u003eAntenna Outputs: 2\u003c\/li\u003e\n\u003cli\u003eTuning Time: 0.5–6 seconds (full) \/ 0.1 seconds (memory)\u003c\/li\u003e\n\u003cli\u003ePower Requirements: 11–16V DC, 750mA max during tuning\u003c\/li\u003e\n\u003cli\u003eDimensions (D × W × H): 267 × 216 × 64mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LDG Electronics","offers":[{"title":"Default Title","offer_id":57609632809304,"sku":"MOON-18-166","price":409.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/at-600proii-w-e1536187662438.jpg?v=1782918754","url":"https:\/\/kamsat.co.uk\/products\/ldg-at-600-proii-automatic-antenna-tuner","provider":"Kamsat","version":"1.0","type":"link"}
