Vine Antennas DU-1500T Antenna Tuner & SWR Meter | 1.8–30 MHz | 2kW Max

The Vine Antennas DU-1500T is a high-performance manual antenna tuner and SWR/power meter, designed to optimize the efficiency of your transmitter, antenna, or SWL receiver. With precision impedance matching and built-in SWR and power metering, the DU-1500T allows you to achieve the best possible match across HF frequencies from 1.8 to 30 MHz.

Ideal for both amateur and professional use, this heavy-duty tuner supports up to 2 kW of power and features a highly flexible tuning system with dual capacitors and a comprehensive antenna switching system.

 


🔧 Key Features of the Vine Antennas DU-1500T:

  • Wide Frequency Range:
    Tunes continuously from 1.8 MHz to 30 MHz, perfect for HF operation.

  • High Power Handling:
    Rated for 1500W continuous, with a maximum of 2 kW PEP.

  • Precision Impedance Matching:
    Adjustable input and antenna capacitors (4.5kV, 330pF each) help fine-tune your system for optimal SWR.

  • Cross-Needle Power & SWR Meter:
    Displays forward and reflected power in real-time, with accurate SWR readings at the needle intersection.

  • Multiple Output Modes:
    Five-position ceramic antenna switch supports:

    • Tuned Coax 1

    • Tuned Coax 2

    • Bypass

    • Coax 1 Direct

    • Coax 2 Direct

    • Plus a Tuned Balanced Line + Coax 1 mode for twin-lead or wire antennas.

  • Built-In 4:1 Balun:
    Easily tune balanced antennas using the high-voltage ceramic terminals.

  5. Range Selector:
    Switches between 200W and 2kW meter ranges.


🛠️ Installation & Tuning Guidelines:

  • Connect the transmitter to the RF Input using short coax.

  • Attach antennas to Coax 1, Coax 2, or the Balanced Output, depending on type.

  • Use the Output Selector to choose the correct tuning path.

  • Adjust the Input and Antenna controls while monitoring the SWR meter to reach the lowest possible SWR, ideally 1:1.

⚠️ Important: Always begin tuning with transmitter output at 50–100W. Do not exceed 1500W average. Never operate with the cover removed.


Safe Operation Notes:

  • Do not touch the balanced or end-fed antenna terminals during transmission—high RF voltages may cause burns.

  • When using a balanced line, install the jumper at Coax 1 and set the selector to “Tuned Coax 1.”

  • For wire antennas, use the ceramic terminals without the jumper.

  • A dummy load can be connected to the BYPASS port for safe tuning or testing.
