This desktop tuner covers all frequencies from 1.8 – 54 MHz, and will automatically match your antenna in no time. Updated features include an LED indicator for antenna selection and an LED to indicate when in bypass. It features a two-position antenna switch, allowing you to switch instantly between two antennas. The AT-100ProII 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-100ProII includes 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 “know” your operating band and frequency. Whenever you transmit on or near a frequency you’ve used before, the AT-100ProII 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-100ProII uses latching relays which retain the tuned configuration indefinitely even when powered down. The AT-100ProII 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. ## Features - LDG AT100ProII is the next step in the evolution of the automatic tuner.
