MAT-Tuner mAT-125E Portable Automatic HF Antenna Tuner, The mAT-125E is a versatile automatic tuner, which can be used in almost all types of transmitters. It 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. 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.

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

Special charger attached to the tuner,8.4V 1.0A. Please do not use other chargers to charge, which may put tuners in danger.
