The LDG AT-100Pro is the next step in the evolution of the automatic tuner. 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.

Bar Code/EAN:
Excellent works well but read instructions
Ideal for the IC-7300 Because it has it has Antenna 1 and Antenna 2 SO239s. Needs time to learn your antenna obviously. Review by Debbie / (Posted on 31/07/2020)
