The LDG AT-100 Pro is the next step in the evolution of the automatic tuner. This desktop tuner covers all frequencies from 1.8-54 MHz, and will automatically match your antenna in no time.

This unit has 2 antenna sockets making ideal for use with radios like FT-897/857/IC-7000/IC-706 as it solves the HF/6m antenna problem. When used with a 6/2 & 70cm antenna and the MX-62 you will still have an HF socket free.

The LDG AT-100Pro is the next step in the evolution of the automatic tuner. This desktop tuner covers all frequencies from 1.8 54 MHz, and will automatically match your antenna in no time.
It features a two-position antenna switch, allowing you to switch instantly between two antennas. The AT-100Pro requires just 1 watt for operation, but will handle up to 125 watts, making it suitable for everything from QRP to a typical 100 watt transceiver.
The AT-100Pro includes over 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-100Pro "know" your operating band and frequency. Whenever you transmit on or near a frequency you've used before, the AT-100Pro can retune from memory almost instantly.

Rugged and easy-to-read LED bargraphs show power and SWR, and a Function key on the front panel allows you to access data like mode and status. The AT-100Pro uses latching relays which retain the tuned configuration indefinitely even when powered down; current draw when not tuning is effectively zero.

The AT-100Pro uses LDG's state-of-the-art processor-controlled Switched-L tuning network. It will match dipoles, verticals, inverted-Vees or virtually any coax-fed antenna. With an optional LDG balun, you can also use longwires or antennas fed with ladder-line.

Control from the front panel is simple and straightforward; just press Tune while transmitting a carrier, and the AT-100Pro will begin an automatic tuning cycle. For more integrated operation, optional interfaces are available for most Icom, Kenwood, Yaesu and Alinco transceivers. With the interface, a single button-press transmits a carrier, executes a tuning cycle and returns the radio to its original power and mode
