LDG Electronics AT-1000ProII Automatic Antenna Tuner 1kW





AT-1000ProII: The LDG AT-1000ProII is our flagship automatic antenna tuner. The AT-1000ProII has an Auto mode that automatically starts a tuning cycle any time the SWR exceeds a limit you set. Also, there are provisions for two antennas; you can switch between them any time you need. For each antenna, there are 2,000 memories that store tuning parameters for almost instantaneous tuner setting whenever you transmit on or near a frequency you’ve used before. Just key and it tunes! The AT- 1000ProII will operate at any power level between 5 and 1,000 watts peak RF input.
The AT-1000ProII will tune from 1.8 to 54.0 MHz continuously, and will match an amazing range of antennas, from Yagis and dipoles to inverted-Vs and slopers; virtually any coax-fed antenna from 6 to 1000 ohms impedance (16 – 150 ohms on 6 meters). Tuning time is usually under 10 seconds. If you’re transmitting near a frequency with stored tuning parameters, it will set those parameters in under 0.2 seconds. Longwires or antennas fed with ladder line require an external balun.
The AT-1000ProII has a large, easy to read bar-graph wattmeter that show forward and reverse power with two selectable ranges (100 and 1,000 watt scales) as well as an SWR meter. The AT-1000ProII will interface with many popular transceivers so you can start a tuning cycle with the radio’s TUNE button. Dedicated control buttons on the tuner allow you to fine-tune capacitance and inductance on those rare occasions when the AT-1000ProII can’t find a perfect match by itself.
