Mat‑tuner MAT‑125E Portable Automatic HF Antenna Tuner

The MAT‑Tuner mAT‑125E is a portable automatic HF antenna tuner designed for use with a wide range of transmitters. It can automatically tune antennas across the entire HF spectrum plus 6 meters, supporting power levels up to 120 watts. Compatible with many antenna types including dipoles, verticals, Yagis and most coax‑fed antennas, the mAT‑125E excels at matching a broad range of impedances, often surpassing the performance of built‑in radio tuners.

Equipped with 16,000 frequency memories, the mAT‑125E features “Memory Tune” functionality to quickly recall previous tuning parameters when operating on or near a previously tuned frequency. When no memorised settings exist, the tuner performs a full tuning cycle and stores the parameters for future recall on subsequent tuning cycles at that frequency. This intelligent learning capability allows the mAT‑125E to adapt to different bands and frequencies over time.

The mAT‑125E operates without a data cable and only requires a 50‑ohm RF cable to connect to the transmitter. The tuner is supplied with two 18650 Li batteries, removing the need for an external power supply and ensuring convenient portable use. A dedicated charger is included, and the tuner utilises a latching relay for reliable, long‑lasting performance when fully charged. For safety and proper operation, the mAT‑125E must be charged only with the supplied special charger rated at 8.4 V 1.0 A.
