LDG Electronics AT-100ProII Antenna Tuners are the next step in the evolution of the automatic tuner. These desktop tuners cover all frequencies from 1.8 to 54 MHz and will automatically match your antenna in no time.

These tuners feature a 2-position antenna switch, allowing you to switch instantly between two antennas. Updated features include an LED indicator for antenna selection and an LED to indicate when in bypass.

AT-100ProII tuners require just 1 watt for operation, but will handle up to 125 watts, making them suitable for everything from QRP to a typical 100 watt transceiver. These tuners include 2,000 memories for each antenna; automatically storing tuning configurations for each frequency and band as you use them.

Frequency-sensing circuitry lets the AT-100ProII tuners "know" your operating band and frequency. Whenever you transmit on or near a frequency you've used before, AT-100ProII tuners can retune from memory almost instantly.

Rugged and easy-to-read LED bar graphs show power and SWR, and a function key on the front panel allows you to access a data-like mode and status.
AT-100ProII tuners use latching relays, which retain the tuned configuration indefinitely, even when powered down. They use LDG's state-of-the-art, processor-controlled Switched-L tuning network. They will match dipoles, verticals, inverted Vs, or virtually any coax-fed antenna.

Features include:

* 1 to 125 watt power range (SSB and CW), 100W on 6M
* Tuning time 0.5 to 6 seconds full tune, 0.25 sec memory
* Selectable user parameters: auto/semi, 125/12.5 watt scale, auto-tuning threshold, and more
* Tunes 6 to 1,000 ohm loads (16 to 150 on 6M)
* Optional external balun allows tuning random-length, long wire or ladder line fed antennas
* Includes DC power cable
* Power requirements: 11 to 16V DC at 500 mA maximum

Note: For additional information, please look at the files under the "Documentation" tab.

If your rig doesn't have a built in tuner, or lacks the wide range required for some applications, consider LDG Electronics AT-100ProII Antenna Tuners from DX Engineering!

Nice ungrade from the IT-100

DX EngineeringDX Engineering Verified Purchase

LDG-AT-100PROII
I’m mainly an Icom guy running some 7100’s and a 7300. I bought (2) IT-100’s to use with the 7100’s and when I bought the 7300 I just used one of the IT-100’s that I purchased for one of the 7100’s. The IT-100 works fine with either of those radios but I decided I wanted to get another tuner just for the 7300. After looking into the AT-100PRO II it appeared to be an upgrade to the IT-100. The AT-100PRO II has an LED bar graph to show power output and SWR. It has two antenna connections that come in handy when I want to switch from my end fed wire over to my 6m vertical. Unlike the IT-100 that requires you to press the Tune button every time you change bands, The AT-100PRO II will automatically tune when you key up and start talking. The tune button on the radio will still put it in a tuning cycle but it’s good to know that if your forget, the tuner will tune on its own. I’m not knocking The IT-100’s, the AT-100PRO II is just a little more feature rich.
