ZEUS ATU-1200X COUPLER board WITH REMOTE CONTROL
1200W Automatic L-Network Antenna Tuner/Coupler with Automatic 9:1 & 4:1 UNUN Switching
The ZEUS ATU-1200X is a high-power external automatic antenna tuner/coupler designed for installation at the antenna feedpoint. It is built for serious HF operators who require reliability, precision, wide matching capability, and convenient remote control.
Using a robust, high-efficiency L-network topology, the ZEUS ATU-1200X provides precise impedance matching from 1.5 to 30 MHz, with very fine tuning resolution and 25 memory channels for fast recall of previously found tuning solutions.
NEW — Automatic 9:1 & 4:1 UNUN
The upgraded ZEUS ATU-1200X features an integrated automatically switchable 9:1 and 4:1 UNUN.
The tuner intelligently selects the appropriate configuration when required, extending its matching capability for antennas with higher impedance, including:
End-fed wire antennas
Long-wire antennas
Multiband wire antennas
Non-resonant antennas
The intelligent tuning algorithm gives priority to the most efficient matching configuration. Whenever possible, the tuner keeps the UNUN bypassed to minimize unnecessary losses.
Wi-Fi Remote Control
The ZEUS ATU-1200X is designed for simple and flexible control through an integrated Wi-Fi web interface.
No dedicated application or special control software is required. Simply connect to the ATU through Wi-Fi and access the control interface using a standard web browser from:
PC
Laptop
Smartphone
Tablet
The web interface provides convenient access to the tuner's functions and settings, allowing the ATU to be controlled remotely from your device.
Auto on-line firmware update funtion.
NEW — FINE TUNE Function
In addition to fully automatic tuning, the ZEUS ATU-1200X introduces a new FINE TUNE function that gives the operator direct control over the tuning components.
With Fine Tune, you can:
Manually adjust the inductance and capacitance values
Fine-tune the antenna to achieve the desired SWR
Experiment with different tuning combinations
Observe how the antenna responds to different values
Analyze the behavior of your antenna system
Find a preferred tuning solution manually
This makes the Fine Tune function useful not only for achieving the best possible match, but also as a powerful antenna experimentation and optimization tool.
For normal operation, simply use AUTO/MANUAL mode.
The AUTO function start tuning when antenna swr is 1,8 or more.
The MANUAL function can start tuning at any level when user press TUNE button.
For users who want complete control and the ability to explore the antenna's behavior, FINE TUNE mode provides direct manual adjustment.
