|Amateur Antenna Tuners|
The LDG AT-100 Pro2 is the next step in the evolution of the automatic tuner. The AT-100 Pro2 keeps all the features of the older AT-100 Pro, but adds an antenna indicator and a bypass indicator on the front panel. This desktop tuner covers all frequencies from 1.8 to 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-100Pro2 requires just 1 watt to operation, but will handle up to 125 watts, making it suitable for everything from QRP up to a typical 100 watt transceiver.
The AT-100 Pro2 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-100 Pro “know” your operating band and frequency. Whenever you transmit on or near a frequency you have used before, the AT-100Pro 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 data like mode and status. The AT-100Pro2 uses latching relays which retain the tuned configuration indefinitely even when powered down; current draw when not tuning is effectively zero. The AT-100Pro2 uses LDG’s state-of-the-art processor-controlled Switched-L tuning network. It will match dipoles, verticals, inverted-Vs or virtually any coax-fed antenna. With an optional LDG balun, you can also use long wires 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-100Pro2 will begin an automatic tuning cycle. With the interface, a single button-press transmits a carrier, executes a tuning cycle and returns the radio to its original power and mode. Two year transferable limited mfg. warranty. Radio cables are not included (see below).
