The mAT-10 is a tuner designed for YAESU FT-817/818, it can also be used in other QRP transceivers. When it is connected to FT-817/818 through a dedicated control cable, it is a dedicated tuner, which can achieve convenient "one-key tuning". If no control cable is used, it is a universal QRP tuner for all low-power transceivers.
The tuner can work within the range of 1.8MHz to 54MHz, at power levels up to 30 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 tuner has two 10440 lithium batteries installed inside, and uses a magnetic retainer relay that saves electricity very much. It can be used for a long time after it is full of electricity.
As you can see, the shell of the mAT-10 is carved out of a whole piece of aluminium, its surface is oxidized to black, and the text on the front panel is carved by laser. It's very small, delicate, beautiful and portable. We believe you will like it.
