LDG AT 100 Pro II Automatic Antenna Tuner
The LDG AT-100ProII is the next step in the evolution of the automatic tuner. This desktop tuner covers all frequencies from 1.8 äóñ 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 äóìknowäó� your operating band and frequency. Whenever you transmit on or near a frequency youäó»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 LDGäó»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.1 to 125 watt power range (SSB and CW), 100W on 6M.
