Building on the success of the AT-1000Pro, LDG Electronics has refined and
expanded its flagship 1KW tuner. The new AT-1000ProII
keeps many of the same features of the previous model, but simplifies the
operation. With the two position antenna switch there are 2,000 memories that
store tuning parameters for almost instantaneous memory recall 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
The AT-1000ProII has a large, easy to read bargraph with two selectable scale ranges (100 and 1,000 watts) as well as SWR
meter. The optional M-1000 4.5" analog meter shows FWD (100 and 1000W scales), REV, or SWR in Peak or Average. The AT-1000ProII will interface with many popular transceivers, enabling
their TUNE button to control the AT-1000ProII’s 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.
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.
