Remote Tuner Overview
Single-Cable Power & Control
The mAT-10R is an automatic tuner powered via the feedline. When using it, no additional control or power cables are required. It must be used together with a Bias-Tee such as the mAT-4117. This single-cable solution simplifies installation and allows remote placement of the tuner near the antenna.
Important Note
The tuner uses a magnetic latching relay. When operating the tuner, please do not place it near strong magnets, especially magnetic brackets, otherwise it may be affected and cause it to malfunction.
The mAT-10R is a newly designed universal QRP remote automatic antenna tuner compatible with various common QRP HF transceivers. It can also be used with HF transceivers capable of up to 100W RF output power, provided that the RF power input to the tuner is limited to no more than 10W.
The mAT-10R is a universal QRP remote automatic antenna tuner designed for QRP HF transceivers. The tuner is powered through its coaxial feedline. It must be used with a Bias-Tee unit (such as mAT-4117), but other brands of bias-tees are also compatible.
The mAT-10R features two types of antenna interfaces: a BNC coaxial connector and banana jack sockets. You can connect the antenna feedline using the tuner's BNC connector, or use the banana jacks to directly connect a wire antenna. Its compatible antenna types and impedance range are exceptionally broad, far exceeding those of many other tuners you may have considered—including many built-in transceiver tuners.
Connector Description
| Top Panel - COAX | BNC coaxial antenna connector |
|---|---|
| Top Panel - WIRE | Red banana jack for wire antenna |
| Top Panel - GND | Black banana jack for ground connection |
| Bottom Panel - RF-IN&DC | RF and DC input (on a single feedline) |
Remote Operation Advantage
As a remote tuner, the mAT-10R can be placed directly at the antenna feed point. This minimizes feedline losses by matching the antenna impedance at the antenna end rather than at the transceiver end. The single coaxial cable carries both RF signals and DC power/control signals, eliminating the need for separate control cables running to the remote location.

Bias-Tee Units (Required)
Note: The mAT-10R must be used with a Bias-Tee unit for operation. Compatible units include:
- mAT-4117 - Professional Bias-Tee with filtering
- Other brands of bias-tees are also compatible
The Bias-Tee injects DC power onto the coaxial cable that carries RF signals to the remote tuner. For more information about the mAT-4117 , please refer to their respective manuals.
