LDG has redesigned the AT-600Pro to be the AT-600ProII. They've added an option to use an external 4.5 inch LED backlit analog meter (similar to the AT-1000ProII external meter) that reads forward and reverse power as well as SWR. The tuner and the meter are independently selectable, so you could show average power on the bargraph and peak reading on the meter.

The AT-600ProII will handle up to 600 watts SSB and CW and 300 on RTTY (1.8 - 30 MHz) and 250 watts on 54 MHz. It features LDG's state-of-the-art, processor-controlled Switched-L tuner. It will match virtually any kind of coax-fed antenna, including Yagis, dipoles, inverted V's, slopers, loops, just about anything. It will typically match a 10:1 SWR down to 1.5:1 in just a few seconds. You can also use the
AT-600ProII with longwires, random wires and antennas fed with ladder line just by adding a balun.

The AT-600ProII features two antenna ports with a front-panel indicator showing which is in use, and separate memory banks for each antenna. Easy to read LED bar-graph meters showing RF power, SWR and tuner status, tactile feedback control buttons and an LED bypass indicator complete the user interface. Any power source from 11-16 volts DC can be used; the AT-600ProII only draws up to 750mA.


The AT-600PROII will tune from 1.8-54MHz continuously and will handle up to 600 watts. Designed to work with the mid-sized amps.
