The LDG AT-1000ProII is our flagship automatic tuner. Made for QRO hams, it will handle 1,000 watts SSB or 350 watts FM/Digital from 1.8-54 MHz.
Like most LDG tuners the AT-1000ProII operates automatically, beginning a tuning cycle whenever the SWR exceeds a preset limit. To protect its circuitry, the tuner will not tune at power levels above 150 watts; 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 whenever necessary.
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 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.
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.
All LDG tuners come with a two year fully transferable warranty, and LDG’s legendary customer service. Contact your LDG dealer to order.
When I received my call sign a few years back, I was flooded with purchases of junk. Fast forward to 2019. I decided I wanted to build another option, not a dealer who has the same stuff as everyone else, but a dealer who actually uses what he sells. And that’s exactly what I do. If you see a product on this page or one of our tables at Hamfest, you can bet we have tried it and like it. From Radios to connectors we strive to bring you QUALITY. Sure, you can find it cheaper and we understand that, but if you don’t want to buy it again in 6 months, take a look at what we sell and have already approved. I am always just a phone call away.
