The AT-1000ProII provides fully- and semi-automatic antenna tuning across the entire HF spectrum plus 6 meters, at power levels up to 1000 watts (250 W on 6 m). It will tune dipoles, verticals, Yagis, or virtually any coax-fed antenna. It will match an amazing range of antennas and impedances, far greater than some tuners you may have considered, including the built-in tuners on many transceivers.
The AT-1000ProII is designed to handle 1000 watts of output power, and is ideal for use with small outboard linear amplifiers rated up to 1000 watts, or even newer high power .
Features:
Easy to Read Bar Graph
Tune from 1.8 to 54 MHz
Dual Antenna Switch
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 radios TUNE button. Dedicated control buttons on the tuner allow you to fine-tune capacitance and inductance on those rare occasions when the AT-1000ProII cant find a perfect match by itself.
The AT-1000ProII features two output connectors so you can easily switch between two antennas. There are 2,000 memory locations for each antenna, allowing nearly instant returning on frequencies you've used before.
The AT-1000ProII will tune from 1.8 to 54.0 MHz continuously, and will match Yagis, dipoles, inverted-Vs, slopers, or virtually any coax-fed antenna from 6 to 1000 ohms impedance (16 150 ohms on 6 meters). Tuning time is normally under 10 seconds; memory tuning time is under 0.2 seconds. Longwires or antennas fed with ladder line require an external balun, not included.
