mAT-125E HF-SSB General Automatic Antenna Tuner

INTRODUCTION

The mAT-125E is an automatic tuner intended for use with HF transceivers. The mAT-125E can
work within the range of 3MHz to 54MHz.

The mAT-125E provides automatic antenna tuning across the entire HF spectrum plus 6 meters,
at power levels up to 120 watts. It will tune dipoles, verticals, Yagis, or virtually any coax-fed
antenna. It will match an amazing range of antennas and impedances, far greater than some
other tuners you may have considered, including the built-in tuners on many radios.

The mAT-125E also features advanced memory tuning, providing 16000 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 mAT-125E has 16,000 frequency memories. When tuning on or near a previously tuned
frequency, the mAT-125E uses “Memory Tune” to recall the previous tuning parameters in a
fraction of a second. If no memorized settings are available, the tuner runs a full tuning cycle,
storing the parameters for memory recall on subsequent tuning cycles on that frequency. In this
manner, the mAT-125E “learns” as it is used, adapting to the bands and frequencies as it goes.
Two 18650 lithium batteries installed inside tuner to provide power for the tuner. Tuner is
charged, can only be used with prescribed charger, the charger has the highest output voltage of
8.4VDC. mAT-125E uses little power while tuning, and essentially zero power when in standby,
when the equipment is full of electricity, it can work for a long time. These 18650 lithium
batteries do not have a protective circuit, and the protection function is completed by tuner.
