mAT-1F Automatic Antenna Tuner for Yaesu FTX-1 – HF/50MHz, 10W, Long Wire & 50Ω Compatible ATU

The mAT-1F is a compact automatic antenna tuner specifically designed for Yaesu FTX-1 transceiver, covering HF and 50MHz bands with 10W power handling. Compatible with both long wire antennas and 50Ω coax-fed antennas, it enables portable QRP operations with fast auto-tuning in 1-3 seconds for optimal SWR performance.

Overview

The mAT-1F is a dedicated automatic antenna tuner engineered exclusively for the Yaesu FTX-1 portable QRP transceiver, providing seamless integration and optimal performance for HF and 50MHz amateur radio operations. This compact ATU enables operators to efficiently match various antenna types including random long wires, end-fed antennas, verticals, and standard 50Ω antennas, making it an essential accessory for field operations, SOTA activations, POTA expeditions, and emergency communications.

Designed with precision matching circuitry and fast microprocessor control, the mAT-1F automatically tunes your antenna system to achieve the best possible SWR across the entire HF spectrum from 1.8MHz to 54MHz, ensuring maximum power transfer and protecting your FTX-1 transceiver from high SWR conditions.

Technical Excellence

The mAT-1F employs a sophisticated L-network matching topology with high-Q inductors and low-loss capacitors, controlled by an advanced microprocessor algorithm that rapidly calculates and implements the optimal matching solution. The tuner features latching relays that maintain settings without power consumption, maximizing battery life during portable operations.

Temperature-compensated components ensure stable performance across wide environmental conditions, while RF sensing circuitry automatically initiates tuning when needed. The unit includes comprehensive SWR protection, preventing damage from extreme mismatches or accidental transmission into an open circuit.

Installation & Operation

Setup is straightforward with direct connection to the Yaesu FTX-1 using the supplied interface cable. The tuner draws power directly from the transceiver, eliminating the need for separate batteries. Simply connect your antenna to the ANT port, attach a suitable ground or counterpoise if using end-fed configurations, and press the tune button to initiate automatic matching.

The intelligent memory system learns your operating patterns, storing tuning solutions for frequently used frequencies. This enables near-instantaneous band changes without manual intervention, perfect for contest operations or rapid deployment scenarios.

Applications & Use Cases

Portable QRP Operations
Ideal for backpackers and field operators who need lightweight, efficient antenna matching without carrying multiple resonant antennas. The mAT-1F allows a single wire antenna to cover all HF bands plus 6 meters.

Emergency Communications
Essential for EmComm stations where rapid deployment with non-resonant antennas is critical. The auto-tuning capability ensures reliable communications regardless of available antenna options.

SOTA/POTA Activations
Perfect for Summits On The Air and Parks On The Air activators who need quick setup and multi-band capability from compact antenna systems.

Marine & RV Mobile
Excellent for installations where antenna length is restricted by physical constraints, allowing efficient operation on all bands with compromise antennas.
