Featuring instant two-antenna switching, advanced memory tuning with 2,000 presets, and intuitive LED indicators, it ensures rapid, efficient tuning with minimal power consumption. Built for reliability and portability, it’s backed by a 2-year warranty and legendary LDG support. ## Description The LDG AT-100ProII is a general purpose automatic tuner suitable for many amateur applications. It covers 1.8-54 MHz, and features a two-position antenna switch allowing instant switching 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. Like most LDG tuners the AT-100ProII operates automatically, beginning a tuning cycle whenever the SWR exceeds a preset limit. The AT-100ProII also features LDG’s advanced memory tuning, providing 2,000 memory locations; when tuning near a previously used frequency it will recall the settings for nearly instant tuning. It learns your favorite frequencies and bands as you use it. You can also start a tuning cycle manually whenever necessary. Large, easy-to-read LED bargraphs show forward and reverse power in peak or average mode, and SWR. Two power scales are provided: 12.5 watts and 125 watts. The bargraphs also indicate tuner status and input confirmations. 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. It handles 100 watts SSB or 50 watts FM/Digital when used with a solid-state transceiver; vacuum tube transmitters cut the power ratings about in half. The AT-100ProII uses latching relays which retain the tuned configuration indefinitely even when the unit is powered down. The latching relays also enable extremely low power consumption; when not actively tuning the AT-100ProII draws next to no power at all. This makes it suitable for portable or mobile operation from batteries. All LDG tuners come with a two year fully transferable warranty and LDG’s legendary customer service. ## Features - It covers 1.8-54 MHz, and features a two-position antenna switch allowing instant switching between two antennas. - For Dipoles, Verticals, Vs, Beams or and Coax Fed Antenna - Power requirements: 11 to 16 volts DC at 500 mA Max. - 125 Watts SSB/CW, 30W Digital - Easy to read LED bar-graph display for RF power, SWR, status.
