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 all 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
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
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. 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.
All LDG tuners come with a two year fully transferable
warranty, and LDG’s legendary customer service. Contact your LDG dealer to
