The LDG AT-200ProII is a general purpose automatic tuner suitable for any amateur application. It covers 1.8-54 MHz, and features a two-position antenna switch allowing instant switching between two antennas. The AT-200ProII requires just 5 watts for operation but will handle up to 250 watts, making it ideal for the new generation of higher powered transceivers, or for QRP operations that sometimes use a small amplifier.
Like most LDG tuners the AT-200ProII operates automatically, beginning a tuning cycle whenever the SWR exceeds a preset limit. The AT-200ProII 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 power in peak or average mode, and SWR. Two power scales are provided: 25 watts and 250 watts. The bargraphs also indicate tuner status and input confirmations. The AT-200ProII 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. All LDG tuners come with a two year warranty, and LDG’s legendary customer service.
Please Note When used with radios like the IC-7300,FTDX10 or TS-890 in bypass mode the tuner will pass 70MHz with minimal loss but will not tune at that frequency
