New version with the USB-C type charging port.

The mAT-125E is a versatile automatic tuner, which can be used in almost all types of transmitter. It provides automatic antenna tuning across the entire HF spectrum, 1.6 - 54 MHz, plus 6 meters, at power levels up to 120 Watts. It will tune dipoles, verticals, yagis, or virtually any coax-fed antenna. The mAT-125E 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.

The tuner does not require a data cable to be connected, but only a 50 Ohm RF cable to the transmitter, which the user needs to prepare themselves. Use a good quality cable and make sure the connectors are connected in the right way.

The mAT-125E contains two 18650 Li batteries, which do not need an external power supply, this makes it easy to use the mAT-125E. And uses a latching relay that works very long time when charged.

Before you use the tuner for the first time after you receive it, the tuner needs to be charged to activate the internal battery protection circuit. During transportation, the tuner is in a protective state and cannot be turned on unless you charge it. You need to do the same after you change the battery.

The tuner uses the USB-C type charging port, so users can easily use the mobile phone charger to charge the tuner. An USB-C type charging cable is included.

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