mAT-125E
HF-SSB General Automatic Antenna Tuner
Instruction Manual Version V3.0
INTRODUCTION
mAT-125E is a universal automatic antenna tuner that can be used in most HF transceivers. It
has a working frequency range of 1.6-54MHz and a maximum allowable RF power of 120 watts.
It has built-in lithium batteries, does not need external power supply, and is very convenient to use,
especially in outdoor portable applications. The mAT-125E does not need a control cable to
connect the transceiver. It only needs an RF cable to connect the transceiver to work well.
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 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 get a lower SWR.
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, the lithium battery can work for a long time after it is fully charged. It is
very suitable for outdoor use. Special chargers are provided with tuners. You must use its own
charger to charge the tuner. It is dangerous to charge with an incorrect charger.

NOTE: Before the first use or after the battery is replaced, the tuner must be charged by
the charger to activate the internal protection circuit before it can be used normally.
