Product Description

Time was, 100 watts was a lot of power. Today, more and more transceivers feature 200 watts output. Even though many of these modern radios feature a built-in tuner, it’s range and features are usually quite limited; if you need a tuner, you probably need a better one than they built into the radio. The LDG AT-200ProII is designed for this new generation of rig. It's specifically recommended for Ten-Tec and tube radios.

Many QRP operators have a small 100-150 watt amplifier for times when you need a few more S-units. The AT-200II is ideal for this kind of operation; it’s minimum required power is only 5 watts, but it will handle the higher power as well.

The AT-200II will handle up to 250 watts SSB or CW on 1.8 – 30 MHz, and 100 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 Vs, 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-200ProII with longwires, random wires and antennas fed with ladder line with the optional LDG balun.

Operation couldn’t be simpler: while transmitting a carrier, just press the Tune button. An automatic tuning cycle will begin, then end a few seconds later with the tuner set at the lowest SWR (almost instant for frequencies stored in memory).

The AT-200ProII is the latest in a long line of innovative LDG tuners. Get the most out of your Kenwood, Yaesu, Ten-Tec or Icom radios that operate at higher power.

  2. Best Auto Tuner for TS-480HX 5 Star Review

    Posted by on 15th Jul 2016

    I tried others and this one works the best. Although ou cannot connect it to the radios auto tune button, you can program the PF key on the radio to do the same thing.
    It works and it works fast once a frequency has been memorized. I tune a vertical and a G5RV with it and having the two antenna inputs is convenient.
