The MAT-Tuner mAT-1500 Pro is a high-power automatic antenna tuner designed for modern high-power transmitters and linear amplifiers, handling up to 1,500W PEP across the full 1.8–30 MHz HF band. Compatible with LSB, USB, CW, FM, FSK, and RTTY modes. No control cable is required — operation is via a single multi-function button on the front panel that handles tuning start, online, and offline functions, and doubles as a status indicator. A PTT signal control function automatically interrupts the transmitter's PTT to the power amplifier during a tuning cycle, protecting your amplifier. Important: Tuning power must be 5–15W maximum. Excessive power during tuning will damage the tuner. 16,000 memory channels store LC configuration data for near-instant 100ms recall on previously tuned frequencies. New frequencies tune in typically under 5 seconds. Tuning impedance range is 6–1,000Ω (approx. 10:1 SWR). The housing is machined from solid aluminium alloy — front and rear panels milled from a single piece for maximum rigidity. Suitable for land and marine deployments. Operating temperature: −20°C to +60°C.
