LDG Electronics AT-1000ProII Automatic Antenna Tuners are easy to use! LDG Electronics has refined and expanded its 1 kW automatic antenna tuners. They have retained most of the features of previous successful models, but now have an even easier operation.

These tuners always offer two antenna inputs that are selectable on the front panel with 2000 memories for each antenna. They store setting parameters with a virtually instant memory reminder each time you transmit on or near a frequency you used before. AT-1000ProII tuners will operate at any power level between 5 and 1000 watts.

The AT-1000ProII tuners feature large, easy-to-read LED bargraph counters with two selectable power ranges (100 and 1,000 watts) and the SWR. An optional 4.5-inch M-1000 analog meter displays SWR ranges and either 100 or 1000 watts of forward or reverse power in peak or average mode. The AT-1000ProII tuners will interface with many popular transceivers, allowing "TUNE" push button control of the AT-1000ProII's operation. Dedicated control buttons allow you to fine-tune capacitance and inductance on the rare occasions when the AT-1000ProII does not find a perfect match.

AT-1000ProII automatic antenna tuners will continually tune from 1.8 to 54.0 MHz and offer an incredible range of antennas, from Yagis to dipoles and inverted Vs. Virtually all coaxial-fed antennas can be set, with an impedance of between 6 and 1000 ohms on HF and between 16 and 150 ohms over 6 meters. The initial tuning time is usually less than 10 seconds. If you transmit near a frequency with stored tuning parameters, these parameters will be set in less than 200 milliseconds. The use of long wires or antennas powered by a ladder line will require an external balun, not included.
