This tuner will handle up to 600 watts SSB and CW and 300 on RTTY ( 1.8 -30 MHz) and 250 watts on 54 MHz. They feature LDG's state-of-the-art, processor-controlled Switched-L tuner. Their front panel bar graph meter, and the optional sweep-needle remote meter, displays all tuner and power readings. AT-600ProII tuners will match virtually any kind of coax-fed antenna, including Yagis, dipoles, inverted Vs, slopers, loops just about anything. They will typically match a 10:1
SWR down to 1.5: 1 in just a few seconds. You can also use AT-600ProII tuners with end-feds, random wires, and antennas fed with ladder line just by adding a balun. These tuners feature 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. As with most RF Sensing autotuners, AT-600ProII tuners will automatically tune with any rig without the need for accessory band-switching cables
