The LDG AT-1000ProII is our flagship automatic tuner. Made
for QRO hams, it will handle 1,000 watts SSB or 500 watts FM/Digital from
Like all LDG tuners the AT-1000ProII operates automatically,
beginning a tuning cycle whenever the SWR exceeds a preset limit. To protect
its circuitry, it will not tune at power levels above 150 watts; you simply
bypass your amplifier (or place it in Standby) to complete a tuning cycle using
only the exciter. The AT-1000ProII also features LDG�s advanced memory tuning,
providing 2,000 memory locations; when tuning near a previously used frequency
it will recall the settings for nearly instant tuning. It learns your favorite
frequencies and bands as you use it. You can also start a tuning cycle manually
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 optional M-1000 4.5"
analog meter shows forward power (100 and 1,000W scales), reverse power, or SWR
in peak or average mode. 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.
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 usually under 10 seconds; memory tuning time is under 0.2
seconds. Longwires or antennas fed with ladder line require an external balun,
not included. The AT-1000ProII is intended for use with exciters with no
more than 100 watts output when used with solid-state transmitters; vacuum tube
transmitters cut the power ratings in half.
All LDG tuners come with a
two year fully transferable warranty, and LDG�s legendary customer service.
