LDG Z-100 Plus – Automatic Antenna Tuner


The LDG Z-100 Plus 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 30 watts Digital but requires only 0.1 watts to tune, making it ideal for QRP operation. Use the Z-100 Plus and the Y-ACC interface cable for the new FT-891 mobile HF radio. Like most LDG tuners the Z-100 Plus 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 favourite frequencies and bands as you use it.

The LDG Z-100 Plus requires very little electrical power. It draws about 200 mA when tuning and just about Zero current when receiving or on standby. This feature makes the Z-100 Plus especially suitable for mobile or portable operation. All LDG tuners come with a two-year warranty and LDG’s legendary customer service.
