LDG Electronics AT-1000ProII Automatic Antenna Tuners

LDG Electronics AT-1000ProII Automatic Antenna Tuners are simple to operate! LDG Electronics has refined and expanded their flagship 1 kW automatic antenna tuners. They've retained most of the features of the previous successful models, but now have even easier operation.

These tuners still offer two antenna inputs that are front panel selectable with 2,000 memories for each antenna. They store tuning parameters with virtually instantaneous memory recall whenever you transmit on or near a frequency you've used before. Just key-up and it tunes! AT-1000ProII tuners will operate at any power level between 5 and 1,000 watts peak RF input.

AT-1000ProII tuners have large, easy-to-read LED bar-graph meters that display two selectable power ranges (100 and 1,000 watts), as well as SWR. An optional 4.5 in. analog meter, model M-1000, shows SWR and 100 or 1,000 watt ranges of forward or reverse power, in peak or average modes. AT-1000ProII tuners will interface with many popular transceivers, enabling transceiver "TUNE" button control of AT-1000ProII operation. Dedicated control buttons allow you to fine-tune capacitance and inductance on those rare occasions when the AT-1000ProII can't find a perfect match by itself.

AT-1000ProII Automatic Antenna Tuners will tune from 1.8 to 54.0 MHz continuously, and will match an amazing range of antennas, from Yagis and dipoles to inverted-Vees and slopers. Virtually any coax-fed antenna may be tuned, from 6 to 1,000 ohms impedance across HF, and from 16 to 150 ohms on 6 meters. Initial 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 200 milliseconds. The use of longwires or antennas fed with ladder line will require an external balun, not included.
