Automatic antenna tuner mAT-1500PROII represents the latest model of a high-performance device designed for radio amateurs who need reliable and fast antenna adaptation over a wide range of power and frequencies. It is an automatic tuner with a maximum power of 1500 W PEP (SSB), designed for use with most transceivers and linear amplifiers in bands 1.8 - 30 MHz. Manufacturer Hengshui M a T-Tuner LLC thus expands its family of successful tuners with a professional model suitable for serious HF operation.
Construction and design
mAT-1500ProII is a robust device with aluminum chassis, which combines aesthetics and strength. The front panel made of CNC aluminum contains 4.3-inch LCD high-resolution display (800 × 480 px), which displays data on power, SWR, mode, tuning status, and selected antenna. Control is provided by ten buttons that allow manual tuning, antenna switching, selection of Online/Bypass mode, brightness adjustment, and manual tuning of the LC loop for minimum SWR.
Operating modes
The tuner operates in three modes:
GENER a L - a universal mode for all types of transceivers. Tuning is started manually, the tuner can also be controlled remotely via the interface RS232.
YAESU mode - fully compatible with Yaesu tuners (FC-30, FC-40, FC-50). It is powered directly from the transmitter via a cable m a T-CY, without the need for an external source.
ICOM mod – intended for transceivers ICOM and Kenwood, connection via cable m a T-CI or m a T-CK.
The tuner automatically recognizes the type of connected device and adapts to it. In YAESU and ICOM modes, it turns on and off with the transceiver, while in GENERAL mode, it is activated by a long press of the [PWR/BAC] button.
Power, speed, and accuracy
mAT-1500ProII manages 1500 W PEP in SSB a 800 W in digital modes. Tuning is very fast — usually within 8 seconds, while when using the saved settings, the time is reduced to 0.1 seconds. The tuner can store up to 16,000 memory points, so repeated tuning on known frequencies is practically instantaneous.
In BYPASS mode, the tuner can also be used as precise power and SWR meterThe LCD displays average and peak power (AVG/PEP) with three ranges - 15 W, 150 W, and 1500 W.
Connections and safety features
Connectors are located on the rear panel RF-IN, a NT1/ a NT2, PTT IN/OUT, RS232 REMOTE, as well as ground point (GND)The tuner can switch between two antennas via the [ANT-SEL] button.
An important safety feature is separation of PTT signal during tuningThis prevents the transmitter from producing a signal during the tuning cycle - preventing tuner damage. After tuning is complete, the tuner automatically restores PTT for normal operation.
Power supply ensures 12-14 V DC / 2 A adapter, which is included in the package. Other connecting cables (e.g. mAT-CY, mAT-CI, mAT-CK) are optional accessories.
Practical operation
When tuning in GENERAL mode, the user gradually:
Selects the antenna and power range,
Sets the transmitter to a frequency with 10 W power,
Starts tuning with the [TUNE] button.
If tuning is successful, the tuner will display 'ONLINE'. In case of failure ('BYPASS'), the signal remains connected directly. In YAESU and ICOM modes, tuning is triggered directly from the transceiver, for example with the [TUNE] or [AT] button.
Manual tuning of the LC circuit is also possible during operation using the [LUP], [LDN], [CUP], [CDN] buttons. The tuner also alerts if the input power is higher than 20 W during tuning - it will display an error message and interrupt the process to prevent component damage.
