The mAT-10R is an RF-sensing universal automatic antenna tuner designed specifically for portable QRP operations and remote installation. Its unique feature is being powered and controlled directly via the coaxial cable (requires a Bias-Tee), eliminating the need for additional control cables.
- Frequency range: 1.8 to 30 MHz
- Maximum power: 10 Watts SSB/CW, 5 watts digital modes
- Power via coaxial cable, Bias-Tee required
- Antenna connectors: BNC and banana terminals wire
- Memory: 16,000 channels
- Ultra-compact and lightweight casing (7 ounces)
- Latching relays for power saving
Comes with: mAT-CMB1M coaxial cable (3 ft, UHF male to BNC male).
The mAT-10R from mAT-TUNER is an innovative solution for amateur radio enthusiasts of QRP and field operations (SOTA, POTA, portable). This automatic antenna tuner stands out for its ability to be installed directly at the antenna feed point, thus minimizing losses in the transmission line.
Its major asset lies in its power and control system via a single coaxial cable. It requires the use of a current injector (Bias-Tee), such as the mAT-4117 (sold separately) or any other compatible model, to operate without an additional control cable. Compatible with all QRP HF transceivers (Yaesu FT-817/818, FTX-1 Field, Icom IC-705, Xiegu, etc.), the tuner accepts a maximum power of 10 watts.
The mAT-10R uses latching relays that maintain their state even when unpowered, which is ideal for saving battery in portable use. Warning: Do not place the tuner in the immediate vicinity of powerful magnets or magnetic mounts, as this could disrupt the operation of the relays.
For installation, connect your transceiver to the Bias-Tee, then the Bias-Tee to the RF-IN port of the mAT-10R via a coaxial cable. The antenna can be connected either via the BNC connector (for a coaxial antenna) or via the red and black terminals (for a long wire antenna and its counterpoise).
Does the mAT-10R work without a Bias-Tee?
No, the mAT-10R does not have an external power input or an internal battery. It must imperatively receive its power (7-14V) via the coaxial cable thanks to a current injector (Bias-Tee) like the mAT-4117.
Can I use this tuner with a 100W radio?
Yes, but you must imperatively reduce your transmitter's output power to 10 Watts maximum. Any higher power will irreparably damage the tuner.
What is the difference between MAT-10R and the classic mAT-10?
The classic mAT-10 has an internal battery and a specific control cable for Yaesu FT-817/818. The mAT-10R remote tuner has no battery, is powered via the coaxial cable, and is universal without data control cable for use with any QRP radio.
Can it be used in the rain?
The casing is not waterproof. For permanent outdoor installation or in the rain, it must be placed in an appropriate waterproof enclosure.
How to start a tuning cycle?
Since there is no data control cable, tuning is initiated by transmitting a continuous carrier (CW, AM, or FM) at low power (3-5W) from your radio. The tuner detects the high SWR and automatically starts the tuning cycle.
