Second hand LDG AT-200ProII automatic antenna tuner, designed for amateur radio operators requiring fast, convenient automatic antenna matching with up to 200 watts SSB/CW capability.

The AT-200ProII is an excellent station ATU for HF and 6 metre operation, combining LDG's automatic tuning technology with extensive tuning memories and support for multiple antenna configurations.

Product Description

The LDG AT-200ProII is a versatile automatic antenna tuner designed to provide rapid impedance matching between compatible amateur radio transceivers and antenna systems.

With its higher power capability, the AT-200ProII is particularly well suited to operators running 100W-class HF transceivers who want additional power handling headroom compared with smaller automatic tuners.

Automatic tuning removes the need to manually adjust capacitors and inductors each time the operating frequency or antenna changes. Once activated, the tuner searches for a suitable matching combination and stores successful settings in memory for faster recall when returning to previously used frequencies.

The AT-200ProII also offers two antenna outputs, making it particularly useful for stations operating more than one antenna system.

Automatic Tuning Memories

One of the major advantages of the AT-200ProII is its extensive memory system.

Once a successful antenna match has been established, the tuner can recall previously stored settings when returning to that frequency, significantly reducing subsequent tuning time.

This is particularly convenient for operators frequently changing between amateur bands or using several favourite operating frequencies.

Important Operating Information

An automatic antenna tuner provides impedance matching between the transmitter and antenna system. It does not physically change the antenna's resonant frequency or compensate for an unsuitable or defective antenna installation.

Maximum safe power can vary according to operating mode, frequency and the severity of the antenna mismatch, so the manufacturer's operating limits should always be observed.
