MAT-TUNER
HF-SSB General Automatic Antenna Tuner

INTRODUCTION

The mAT-125E is a universal automatic antenna tuner that can be used with most HF
transceivers. Working frequency range of 1.8-54MHz, 120 watts maximum RF power. Built-in
rechargeable lithium batteries eliminates the need for external 12 vDC power supply.,
The tuner does not need a control cable to connect the transceiver. It only requires
connection to the transceiver via coaxial cable. Tunes dipoles, verticals, Yagis, or virtually any
coax-fed antenna. Matching range of 5-1500 ohms, far in excess of the capability of typical
internal automatic antenna tuners or other external units.
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.
You can also start a tuning cycle manually whenever necessary.
The tuner has four fine-tuning buttons. After automatic tuning, you can make more fine
adjustments manually to adjust for lower SWR if desired.
Two 18650 lithium batteries are installed in the interior of the mAT-125E, which provides
power for the tuner. Because of the use of advanced magnetic retaining relays, the power
consumption of mAT-125E is very small, and lithium battery can power the unit for long periods
of time after it is fully charged. Special chargers are provided with tuners. Use the included
charger only for charging internal batteries.

AN IMPORTANT WORD ABOUT POWER LEVELS

The mAT-125E is rated at 120 watts maximum power input at most. Many ham transmitters
and transceivers, and virtually all amplifiers, output well over 120 watts. Power levels that
significantly exceed specifications will definitely damage or destroy your mAT-125E. If your
tuner fails during overload, it could also damage your transmitter or transceiver. Be sure to
observe the specified power limitations.
