Z-11PRO-II - LDG - VERSION "B" - Automatic antenna tuner - Operates from 1.8 to 54 MHz - Built-in battery case for portable operations

The LDG Z-11ProII is a small, low-cost automatic tuner suitable for any amateur purpose, whether base, mobile or portable. It handles up to 125 watts SSB or CW but requires only 0.1 watts to tune, making it ideal for QRP operation.

Like all Generic LDG tuners, the Z-11ProII can operate automatically, beginning a tuning cycle whenever the SWR exceeds a preset limit. It also features LDGs 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.

The LDG Z-11ProII has features found in larger LDG tuners, such as dedicated buttons for manually fine-tuning the match. This can be useful when tuning an antenna far from resonance. 

The LDG Z-11ProII requires very little electrical power; when not tuning the current draw is negligible. An internal battery holder for eight AA batteries will operate the tuner for a year of normal use. This feature makes the Z-11ProII especially suitable for mobile or portable operation.
