The MAT-Tuner mAT-10 is a compact QRP automatic antenna tuner covering 1.8–54 MHz at up to 30W SSB/CW (5W on keydown digital modes). Designed for one-touch automatic tuning with the Yaesu FT-817 and FT-818 via the included dedicated control cable, it also works with any QRP transceiver by simply pressing the TUNE button on the front panel. Power comes from two internal 10440 lithium batteries (included), with a near-zero current draw when not actively tuning — a single charge can last months. A charging cable is also included. 16,000 frequency memories allow 0.1-second recall on previously tuned settings, with full tuning cycles completing in 0.1–5 seconds. Matching range is 5–1,500 ohms, covering dipoles, verticals, yagis, and virtually any coax-fed antenna. The housing is extruded black oxidised aluminium with an aluminium rear panel and white silkscreened lettering. BNC male connectors on input and output.
